NBR HNBR FKM PTFE Rubber Lip Seal Ring for Hammer Union - Oil and Chemical Resistant Weco Seal

High quality NBR HNBR FKM PTFE Rubber hammer union seals for oilfield

Product introduction

Hammer union seals are used in the connections between flexible hoses or pipes used in the oil drilling industry. The seal provides a critical fluid tight connection within the union hardware. Hammer unions consist of a thread end, a nut end, and a hammer nut that when tightened seal the assembly with the assistance of an elastomer seal. The seal is lipped to prevent it from falling out when inverted.

In the high-pressure, high-stakes world of oil and gas exploration, hammer union seals stand as critical components that ensure the integrity of fluid transfer systems. Designed specifically for the rugged conditions of oilfields, these seals are engineered to fit within hammer unions—mechanical connectors widely used to join drill pipes, wellheads, and production lines. Their primary function is to create a leak-tight barrier against crude oil, natural gas, drilling mud, and other corrosive fluids, even under extreme pressure and temperature fluctuations that define upstream and midstream oil operations.
