Sonkit Metal W-rings are designed to have low load, high spring back performance for high pressure/temperature applications. In service, Metal W-rings are pressure energized by the system which increases the contact stress and further minimizes leakage. The geometry of the Metal W-ring can be designed to meet the requirements for each unique application and can be manufactured in a wide range of sizes.
Specifications:
