An O-ring should always be lubricated with a suitable “assembly grease” before installation. This makes installation easier and also promotes the longevity of the O-ring. <\/span><\/p>\n

Assembly greases for O-rings are essentially divided into two categories<\/b>
1. mineral oil base
2. silicone base<\/span><\/p>\n

Now the question arises: Which assembly grease do I use for which material? <\/span><\/p>\n

As an answer to this question, we have compiled a table with the most important O-ring materials as an overview.<\/span><\/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

Conclusion: <\/b>The wrong assembly grease can have serious consequences, especially with silicone and EPDM.<\/p>\n

No animal or vegetable fats<\/b> or oils may be used with EPDM<\/b>. This is because EPDM swells extremely with this type of medium and soaks up like a sponge.<\/p>\n

With silicone<\/b>, care must be taken not to<\/b> use silicone grease<\/b>. (like with like is not compatible)<\/p>\n

Otherwise, the assembly grease can be freely selected for all other materials listed.<\/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>\n\t\t","protected":false},"excerpt":{"rendered":"
