Customer service lies at the heart of everything we do at Superior.

Our philosophy is based upon three key constituents:

  • Material science and technology
  • Seal engineering
  • High-efficiency manufacturing

The combination of these three factors provides the high integrity of our precision o-rings and seals, and in turn, provides the long term performance and high integrity in our customers products. Our ‘fast response’ culture is applied to each individual factor to help reduce our customers’ overall project lead time.


We actively encourage and cultivate early involvement in customer projects. This helps to ensure that the seal element is optimised within the environment demanded by the customer. This ensures that our products are reliable, fit for purpose, correctly specified with all critical features identified, controlled and costed at an appropriate and agreed level.


We work closely with our customers on all aspects of seal testing and development programs. All testing procedures are carried out to international standards, BS ISO, DIN, ASTM, or to customer specific requirements. We offer a diverse range of compounds to satisfy the majority of market needs.

If a customer has a specific need that cannot be met within our existing elastomer range, we will develop new compound grades at our in-house laboratory. We are able to conduct extensive test programs to fully validate specific elastomers to customer parameters (e.g. temperature/media exposure and mechanical property testing). We will also validate to specific accreditation standards (e.g. EN681, WRAS, DVGW, ACS, KIWA, NSF, EN 549).


Through the customer partnership exchange, we can assist with optimised seal profile design and application.


Our tooling manufacture department designs and machines precision prototype and production moulds to exceed conventional tolerancing. Pilot tooling can be provided economically and rapidly to further expedite customer test programs. With our extensive tooling expertise, we can optimise critical surface features to facilitate reliable function with mating parts.

Staying ahead

Our continuous capital investment program allows us to remain at the leading edge of our field. We continually implement latest technology systems, ensuring batch-to-batch consistency throughout the manufacturing process. With such broad customer support facilities, Superior will always strive to provide added value with our customer programs. Indeed, we find that each new project challenges our thinking and creates a springboard to increasingly enlightened manufacturing practices.
