Hammer union seal

Hammer Seal unions have long been an essential component in oilfield piping systems. In mud fluid drilling operations, where steel tanks connect to pumps, a leak-proof and quickly detachable large-diameter connection is critical. G&B Rubber Products offers hammer seal unions ranging from 6″ to 12″ in diameter. Each union features a solid nitrile O-ring, oil-resistant and designed to lock securely around the outer diameter of the pipe as the hammer nut is tightened, ensuring a reliable seal. All hammer seal unions are rated to withstand pressures up to 500 PSI. Even in misaligned setups, G&B Rubber Products’ Hammer Seal Unions deliver a dependable sealed connection.
