The role of the specialist trade in the sealing world

O-rings are part of a complex system with many influencing factors. Only when the sealing element itself and the installation situation are optimally matched to the operating loads does the concept meet the requirements over the long term.

It is not only the manufacturing, structural design and expert installation of the seals that matter. The trade, as an intermediary between manufacturer and end customer, also plays a major role.

Specialised distributors actively help to shape the technical and economic performance of sealing systems. They deliver consistently reliable quality and support their customers with technical expertise. In this article you will learn what function the trade performs and how a good O-ring supplier supports its customers even more strongly.

The challenges of being an O-ring supplier

Customers' expectations of their O-ring supplier are easy to sum up. It delivers:

  • the right O-ring,
  • in the required quality,
  • in the quantity needed,
  • within the agreed timeframe,
  • at the lowest possible price,
  • with professional advice.

Naturally, meeting these requirements in practice is considerably more complicated than this list suggests.

The O-ring supplier as a service partner

Uncompromising delivery reliability, high availability and trust-building complaint management are among the standards in the trade. Yet although O-rings may appear unremarkable at first glance, they are products that require explanation. This already begins with their numerous fields of application.

A selection of the industries that rely on O-rings:

Mechanical and vehicle engineering
Hydraulics, pneumatics and dynamic sealing points
Electrical engineering
Housings, connectors and sensor technology
Refrigeration and air-conditioning
Refrigerants and changing temperatures
Sanitary and heating
Drinking water, hot water and heating media
Biomedicine and pharmaceuticals
Purity and tested materials
Food
Contact with food and cleaning media
Semiconductor production
Aggressive process media and plasmas

For each of these areas there are specialised solutions whose properties are tailored to the operating conditions. The O-ring and the installation situation must work together optimally under the application conditions.

In many cases this requires certifications that demonstrate specific material behaviour. Only certain materials can withstand aggressive surrounding media, and these in turn place special demands on the design of the installation groove.

It follows that anyone who wants to cover the range of needs of diverse customers has to do more than be a good merchant. With its own expertise in elastomer technology, a good supplier provides comprehensive advice on the design of new sealing solutions.

If the application experts are involved as early as the design phase, they help to design the entire sealing system optimally. This pays off, because it allows costs to be effectively avoided. Conversely, when customers are looking for a suitable seal for an existing sealing point, often only particularly high-quality materials will do the job. Here too, the experts help with their knowledge of failure analysis and recommend the most suitable sealing elements as well as coordinated measures for installation and maintenance. The technical exchange between the distributor on the one hand and the design and maintenance departments on the other is irreplaceable.

Manufacturer network: the basis for success

The specialist trade brings the seal to the customer. To do so, it works together with several O-ring manufacturers, because hardly any single producer covers the entire range of applications with first-class products. Maintaining the partner network is therefore an important task in the technical trade.

With so many supply relationships and products, quality must not slip out of focus. As a customer, you rightly rely on receiving only high-quality O-rings and seals. Accordingly, it is up to the supplier to monitor the function-relevant properties of the products with effective quality assurance measures.

After all, it is the supplier's application experts who recommend specific materials and dimensions for a sealing task. Without the certainty that the products comply with the specified properties, lasting success is not possible.

Competition in the O-ring market

The competitive situation on the global procurement market and the need to open up new sales channels are not specific to the sealing trade. But here too, individual approaches are called for: those who respond better to growing customer requirements create advantages for themselves and their partners.

Service: the all-round carefree package

For the technical trade in seals, this means that the service function retains its importance. The supplier bundles the products of many manufacturers and thereby makes a preselection. Quality has to be actively assured in the process, because buying O-rings is a matter of trust. From manufacturing through storage to correct delivery, error-proof processes are required. Above all in final treatment and dispatch, the individual customer's wishes are decisive.

With flexibility in surface finishing and packaging, a good supplier adapts its products to customer needs. Colour markings and surface coatings make the manual assembly or automated feeding of O-rings easier. An individual packaging design supports efficient stockkeeping at the customer's site. Film bags with the quantity and labelling to the customer's specifications are often the best protection against ageing and effectively prevent mix-ups.

With a flexible service, a supplier creates considerable added value and sets itself apart from competitors worldwide. Especially with a complex task such as finding the right O-ring, customers increasingly rely on competent and comprehensive support.

Quotation management: serving customer needs optimally

The decisive factor is the best possible match between customer needs and the product range. Particularly with seals, this demands a great deal of organisational skill. Because these are the products of highly specialised suppliers, the distributor has to actively shape its supplier network. This is an ongoing task, because industry specialists repeatedly present interesting products with which customer problems can be solved.

Dynamic development of the sealing world

Innovation is not limited to new sealing solutions. Launching new materials or entire sealing systems together with a manufacturer does offer many opportunities for design. In doing so, the distributor bundles the requirements that customers bring to it and helps the new product achieve successful pilot applications.

But innovative processes, too, make a specialist seal distributor the preferred partner. Those who fully exploit the potential of digital process chains offer their customers real-time information on the processing status of their orders, allow orders to be changed at any time and provide intelligent support in selecting the right products. Automation solutions, such as image recognition, make this possible: the profile of a moulded seal can be scanned, for example, in order to then check availability online.
