Replacement Hammer Union Seal for 602/1002/1502, Viton

Hammer Union Seals are used in hammer union-style pipe connections to establish flow lines and prevent leakage. Hammer Unions are made by Weco, FMC, and Kemper Valve among others, and are used in the Oil & Gas Industry, in steel mills, chemical plants, strip mining, and marine dredging.

Oil Baron Supply offers Hammer Union Seals in Nitrile (also known as NBR, Buna, or Buna-N) for standard service, as well as Viton® (also known as fluoroelastomer or FKM) for increased temperature and chemical resistance or HNBR for Sour Gas Service or Teflon (PTFE). In addition to the standard molded rubber seals, anti-extrusion rings can be reinforced in brass Hammer Union Seals or stainless steel Hammer Union Seals.
