100Weco 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.

Hammer union seals are used for hammer joint type pipe connections to establish flow lines and prevent leakage.
JST's back up ring compensate for large temperature fluctuations. Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. Back-up Rings are protective and supporting elements with no sealing function. The back up ring material could be PEEK, modified PTFE.
