Metal Ring Joint Gasket is a high integrity seal and predominantly used in high pressure / temperature oilfield applications and for petrochemical industry, such as valves, piping assemblies, and pressure vessels. Various materials and profiles are available for most-demanded design and operation conditions and conform to API 6A (oilfield use) and ASME B16.20 (general use) standards to fit ASME, BS and DIN flanges. Steel Oval and Octagonal ring joints are in stock and can be interchangeable on the modern flat bottom groove. We could deliver in the short period. Note: the hardness of metal ring joint gasket should lower 15~20 HB than the hardness of applied flange, as the material may harden to damage the flange and affect sealing properties, we DO not recommend to re-use the gasket.

Hollow metal O-ring is made by heat resistant and noncorrosive stainless steel pipe. It is available to have small holes in the inner diameter or outer diameter, when the pressure increasing, the self-sealing function will be work. The hollow O-ring with small holes is specially applied when the pressure over than 70kgf/cm2, the pressure resistant will better than no holes O-ring. Upon customer’s requirement, we also offer O-ring surface coating PTFE or silver.
