Spring-Energized Seals

Polymer Seals with Metal Springs

Seal jacket compounds are made from high-performance polymer resins that are compounded and processed for optimum sealing control and performance in a wide range of critical environments. Through the decades of supporting pioneering industries such as space and aviation, Omniseal Solutions has developed more than 500 custom blends for unique sealing applications. We continue this legacy of engineering excellence and are continually formulating and developing new materials.

The use of our proprietary PFAS-Free* Materials in the jackets of Omniseal^® Spring-Energized Seals, provides excellent chemical resistance and physical, thermal, and tribological properties, making them successful for over 60 years in the industries of space, aviation, industrial, and more.

* 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.

Meldin® materials include a complete range of high-performance solutions with top thermoset polyimides and a diverse array of engineered thermoplastics based on polyphenylene sulfide (PPS), polyetheretherketone (PEEK), and polyamideimide (PAI).

They are used in specialized applications for aviation, semi-conductor and other industries due to their high thermal resistance and excellent mechanical properties at high temperatures.

The 103A polymer seal has a ribbon or helical spring design and is used for static and low speed applications, providing excellent leakage control at high pressures and low temperatures. Being versatile, this seal is not only one of our most valued solutions but also resilient enough to tackle extreme environments like space. 

The 400A polymer seal has a cantilever spring design with a V-Shape and is used in dynamic applications, providing good friction and leakage control at moderate pressures and temperatures. These seals are relied upon in applications such as energy ball valves where resistance to harsh chemicals, sour environment and rapid gas decompression are necessary.

The APS polymer seal has an advanced pitch or coil spring design and is used for minimizing friction in dynamic applications and has a small inner diameter and cross-section. Due to their smaller sizes, they are used often in life science medical device applications, where miniaturization is key.

The RACO^® polymer seal has a U-shaped spring design and is used in extreme face sealing conditions, including cryogenic fluids and high vacuum. It is a heavy duty design that has been proven to be critical in over 60 years of successful space applications.

The flanged heel design is recommended for rotary and oscillatory shaft applications. The flange is clamped in the Omniseal® seal housing to prevent the seal from turning with the shaft.

Omniseal^® seal designs and construction can be adapted to handle a wide range of extreme conditions from cryogenic to high temperatures. These sealing solutions include asymmetric designs or reinforced spring configurations.
