Performance Seals Index

Performance Seals

Rotary, reciprocating and oscillatory motions can typically be sealed with Spring Energized Seals depending on design.
Great performance in compressed gas waterless fracking seals, LPG and Liquid Nitrogen seals,
Outstanding chemical compatibility and extreme low temperature seal, cryogenic seal applications.
Low friction and long service life in demanding application.
Spring Energized Seals can operate < 3,000 psi custom < 60,000 psi.
SES can operate -280o to 500o F custom -400o to 600o F.
Wide range of spring energizing configurations based on application.
Seals are available in Rod and Piston Inside and Outside Pressure and unidirectional sealing configurations.
MSE® Seals, Bal Seals, Variseal®, OmniSeal®, FlexiSeal®.

Designed to extend O-Ring sealing life in dynamic reciprocating applications
Typically suitable for slow and fast reciprocating speeds running dry or lubricated
Pressure up tp 3000 PSI in most applications
Compatible with all O-Ring materials
Cannot be stretched more than 5% during installation.
Not recomended in Rotary or Oscillating Applications

Back-Up Rings used with O-Rings at pressures > 1500 psi or big extrusion gaps
Back-Up Rings are designed to limit O-Ring clearnace gap extrusion.
Available in elastomeric compounds and PTFE Back-Up Rings.
PTFE Back-up rings can be solid, split, spiral, or custom for ease of install.
PTFE Back-up Ring size standards AN6244, AN6246, MS27595, MS28774, MS28782 and MS28783.
Elastomer Back-up Rings are typically contoured to conform with an O-Ring.
Elastomer Back-up Rings fit standard USA and custom O-Ring sizes.
Back-up Rings require wider glands to accommodate.

Centering rings are used to mostly in vacuum fitings to improve seal performance
