100Standard size hammer union seal
Hammer Union Seals are used in hammer union-style pipe connections to establish flow lines and prevent leakage. It is widely used in the oil & gas industry.
The hammer connector for high-pressure equipment has a replaceable lip seal in the female connector. It provides critical fluid tight connections within the union hardware.
Materials available include NBR, HNBR, Viton. 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.
This type is particularly suitable for abrasive high pressure (15000 psi) hammer unions that do not require welded connections. This design provides a strong, permanent end connection without butt welding. The end of the joint is assembled to the pipe in the workshop. Epoxy thread compound is used for fixed connections. Since all threads are isolated from the fluid line, the resulting smooth holes ensure minimum turbulence, reduce flushing and reduce the accumulation of acid, sand, cement or chemicals around the pipe end.

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.
Rod seals are static seals installed in glands or housings to prevent the leakage of fluid from within a cylinder to the outside as the rod cycles.
It is an end face spring energized seal with both rigid and flexible elements, which gives consistent contact at the sealing interface.
Phenolic wear rings are designed with tubing made from fine weave cotton fabric wound on molds and imbued with phenolic resin. It has high mechanical properties, good oil resistance, low water absorption and high wear resistance.
The FDR seal is made of a helical wound spring and a polymer jacket, which is mainly used as a Flange external face seal.
JST FHP series is made of a helical wound spring and a polymer jacket, which is mainly used for piston.
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.
