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.
The PTFE gate valve seat seal is made of durable teflon, it is compatible with the Cameron gate valve type FC, FLS, and used in rotating equipment to minimize o-ring movement.
Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.
JST FHP series is made of a helical wound spring and a polymer jacket, which is mainly used for piston.
The ESA valve rubber seal is a type of Polypak, it combines a rubber o-ring type and a conventional lip type seal to produce a unique sealing device.
In LNG operations, valves can regularly encounter temperatures below -320 F (-196 C) and pressures above 750 pounds per square inch (psi). They are also subjected to periodic variations in temperatures known as “thermal cycling,” which can result in hardware expansion as well as shrinkage and material stresses. These factors make reliable, long-term valve operation an engineering challenge.
Wear rings are used to help keep the piston centered, allowing for even wear and pressure distribution on the seals. Wear rings are used in both piston and rod applications.
