Weco hammer union seals for Oil & Gas

 

The hammer union sealing ring is used for one-way / high-pressure / static sealing. It is used for working conditions with pressure outside. It is widely used in various static sealing and slow speed sealing occasions. It has a good sealing effect for light gas / refrigerant and vacuum, and can also be used in occasions with poor surface finish.

 

Hammer Union Seals help to prevent leakage in hammer union pipe connections and are generally applied in applications within the Chemical Processing, Offshore Drilling, Petrochemical, and Water and Gas industries.

 

JST offers two lines of hammer union seals, one from elastomer, another one from elastomer reinforced with anti-extrusion ring which is normally used for high pressure.

 

JST's hydraulic hammer union seals have a variety of configurations and materials to choose from, including NBR, HNBR and Viton.
