E-FLEX™ Metal E-Rings for Extreme Environments
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)
- Large and segmented diameters available (>2000 mm/ >78.74 in)
