Features & Benifits


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.


• High springback/low load
• Seal profile and wall thickness designed to control loading and springback
• Available for internal and external pressure
• Large and segmented diameters available (>2000 mm)
