Only special O-ring qualities offer the necessary resistance.

Very high heat is usually generated during operation &#8211; often alternating cyclically with thermal conditions well below room temperature.  <\/p>\n<p>This applies to refineries, for example, as well as to food and beverage production. At the same time, the O-rings come into contact with media that can attack the material of the O-ring. Hot water and steam have proven to be particularly problematic in practice. These media must also be handled in power plants and district heating systems. Water temperatures of up to 175 \u00b0C are not uncommon.<\/p>\n<p>In plants for the production of dairy products, for example, O-rings are exposed to intermediate and end products with a high fat content.  <\/p>\n<p>Aggressive media and very hot steam are used to maintain hygienic conditions. High-quality O-rings must be able to withstand these conditions permanently, because the service intervals are long. This results in high downtime costs and costly replacement procedures.  <\/p>\n<p>In many applications, it is also important that the O-ring itself does not affect the contact media. This is required by the strict industry standards.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<div class=\"elementor-element elementor-element-2ea8af4e elementor-widget elementor-widget-menu-anchor\" data-id=\"2ea8af4e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"menu-anchor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-menu-anchor\" id=\"3\"><\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3254dead elementor-widget elementor-widget-spacer\" data-id=\"3254dead\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7b5b01d elementor-widget elementor-widget-heading\" data-id=\"7b5b01d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\"><span style=\"background-color:#fe5050;color: #ffffff;padding: 5px\">#3  <\/span> \n  Damage caused by hot water and steam<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-154fe035 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"154fe035\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2e5db65d elementor-widget elementor-widget-text-editor\" data-id=\"2e5db65d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Long replacement intervals, extreme temperatures and pressures: These are demanding operating conditions. These influences cause the O-ring to lose its elastic restoring force over time. If this is weakened too much, the O-ring cannot withstand mechanical loads and does not adapt sufficiently to the sealing gap.  <\/p>\n<p>The component loses its sealing effect. But hot water and steam also damage the O-ring.<\/p>\n<p>The media cause unsuitable elastomer materials to age very quickly. There are various damage mechanisms. Contact media can penetrate the material of the O-ring and cause it to swell. If the groove is overfilled by a swelling O-ring, gap extrusion can occur when pressure is applied.  <\/p>\n<p>Media also cause a change in the mechanical material properties. This applies, for example, to elongation at break and hardness, two key parameters for the sealing function. Shrinkage, in which aggressive media dissolve formulation components from the elastomer, has the same consequence. In addition to the impairment of the sealing effect, the medium is usually contaminated in an impermissible manner.<\/p>\n<p>Among other things, water contains hardening agents, carbon dioxide and oxygen, which cause metals to corrode. The water breaks down chemical compounds through hydrolysis.  <\/p>\n<p>It gradually degrades many polymer sealing materials, resulting in shrinkage and the associated loss of compression. However, a minimum compression is necessary so that the O-ring can fully develop its restoring force and bridge the sealing gap.  <\/p>\n<p>The mechanisms also work with water vapor. However, the aggressiveness of the medium also depends on the saturation of the water vapor. The degree of saturation expresses how highly concentrated the water vapor is in the air. This is particularly important when using EPDM O-rings. This is because this material has the extremely useful property that its resistance to air is significantly lower than its resistance to steam.<\/p>\n<p>In addition, many systems with hot water and steam have a cyclical sequence of operating phases. Here, extreme heat alternates with cold.  <\/p>\n<p>Low temperatures are generally gentler on the O-rings. However, cyclical operation results in many changes of state, which affect the sealing gap each time. A falling temperature causes the sealing gap to become larger, while the O-ring itself is also subject to thermal shrinkage.  <\/p>\n<p>When the gap is bridged, the resilience of the O-ring is significantly more stressed than at a permanently high operating temperature. This means that leaks can occur during cyclical operation even if the O-ring still has elastic properties.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6ef4ec1c elementor-widget elementor-widget-menu-anchor\" data-id=\"6ef4ec1c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"menu-anchor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-menu-anchor\" id=\"4\"><\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2e54cfb7 elementor-widget elementor-widget-spacer\" data-id=\"2e54cfb7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-1c040547 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"1c040547\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-inner-column elementor-element elementor-element-629c2f4a\" data-id=\"629c2f4a\" data-element_type=\"column\" data-e-type=\"column\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-96868bc elementor-widget elementor-widget-heading\" data-id=\"96868bc\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\"><span style=\"background-color:#fe5050;color: #ffffff;padding: 5px\">#4<\/span> Criteria for suitable O-rings<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-103a26d2 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"103a26d2\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-21f7f14a elementor-widget elementor-widget-text-editor\" data-id=\"21f7f14a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>O-rings suitable for use with hot water and steam are characterized by the fact that they retain their initial properties for as long as possible when exposed to the media.

If air acts on the O-ring in addition to water, this also limits the durability of the O-ring. Resistance data in air above 150 \u00b0C are rare.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-41cdfd15 elementor-widget elementor-widget-menu-anchor\" data-id=\"41cdfd15\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"menu-anchor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-menu-anchor\" id=\"5-2\"><\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6103f879 elementor-widget elementor-widget-spacer\" data-id=\"6103f879\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-757ec3b elementor-widget elementor-widget-heading\" data-id=\"757ec3b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\"><span style=\"background-color:#fe5050;color: #ffffff;padding: 5px\">#5.2<\/span> FFKM O-RInge: High-end solution for hot water applications<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-76ae5d8f elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"76ae5d8f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-640563ac elementor-widget elementor-widget-text-editor\" data-id=\"640563ac\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Together with FKM and FEPM, FFKM is a fluorinated elastomer. These are characterized by a very wide air temperature range.  <\/p>\n<p>O-rings made of FFKM are suitable for continuous temperatures well above 300 \u00b0C. Use with hot water also requires special recipes. The degree of cross-linking and the type of cross-linking in the polymer are just as decisive.<\/p>\n<p>At the same time, FFKM has a very high resistance to aggressive media. Such substances are widely used in the chemical and petrochemical industries, for example. Mineral oil is therefore not a problem for FFKM. Therefore, the comparatively high costs for FFKM O-rings are particularly justified if the sealing elements are exposed to other aggressive media in addition to hot water or steam.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d507d34 elementor-widget elementor-widget-menu-anchor\" data-id=\"d507d34\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"menu-anchor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-menu-anchor\" id=\"6\"><\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1c274c4e elementor-widget elementor-widget-spacer\" data-id=\"1c274c4e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6bcdea73 elementor-widget elementor-widget-heading\" data-id=\"6bcdea73\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\"><span style=\"background-color:#fe5050;color: #ffffff;padding: 5px\">#6<\/span> Challenging operating conditions require precise  \nInterpretation\n<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-25a865db elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"25a865db\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-325207ee elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"325207ee\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-inner-column elementor-element elementor-element-61f7758b\" data-id=\"61f7758b\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-5aa047b9 elementor-widget elementor-widget-text-editor\" data-id=\"5aa047b9\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>When it comes to O-ring seals for hot water and steam, it is not just the choice of material that is decisive.
