WECO Hammer Union Seals
Lip type seal ring is an elastomer component, as a secondary seal to protect metal-to-metal against corrosion, which minimizes fluid flow turbulence while creating a pressure seal. Depending on the union figure it can be a lip type “seal ring” or an “O-ring”. Different material s are available to suit for different fluid service. Buna-N (NBR) is common for standard service, Viton (FKM) for H2S service.
