E-FLEX™ metal E-rings are designed to have a low load, high spring back performance for high-pressure/high-temperature applications. In service, E-FLEX™ metal E-rings are pressure energized by the system which increases the contact stress and further minimizes leakage. The geometry of the E-FLEX™ metal E-ring can be designed to meet the requirements for each unique application and can be manufactured in a wide range of sizes.
FEATURES & BENEFITS
Properties:
High springback/low load
Seal profile and wall thickness designed to control loading and springback
Available for internal and external pressure
Range of materials (Alloy X750, 718, Waspaloy and other exotic metals)
