PFAS-Free* Solutions & Materials

With growing regulation over Per- and PolyFluoroAlkyl substances, a transition towards alternative materials has become critical to supply chain management throughout the industry. Omniseal Solutions partners with our customers and suppliers to find and develop advanced materials & components for critical applications anticipating key changes in our markets.

Due to their unmatched combination of physio-chemical properties, Fluoropolymers, a sub-family of PFAS, have been used by Omniseal Solutions for decades on numerous challenging applications in various Industries. However, other materials have been developed and used already over years across our different markets. The recent changes in the regulatory environment accelerated our efforts towards the research and development of alternative materials for our customers’ applications.

Our teams of engineers are very well known throughout the industry as technology leaders in sealing technology and beyond, through a strong material expertise, a high design creativity coupled with a wide range of application testing and material simulation capabilities. We have developed and continue to invest in diverse production capabilities that provide us with a versatile manufacturing infrastructure able to supply any high performance metal and plastics parts.

You can find more of those alternatives in the page below or contact us to know more and explore the alternatives with our engineers.

* PFAS-Free here means we do not intentionally add PFAS material in the product, but does not exclude the possibility of traces, as these materials are common in the environment.

Omniseal® Metal Axial Seals

Metal Seals For Radial Pressure

Patented lip seals and comma seals can handle limited motions in your systems. Metal axial seals are different from metal face seals due to the top and bottom of the seal's cross-section being squeezed. They are an excellent choice to replace low friction hydraulic seals and standard O-Rings. Axial seals in particular have higher contact load compared to rubber O-Rings and will also have higher frictional drag.


Used in
applications that need higher contact load or frictional drag
