Rubber V Packing hydraulic seals

V Packing consist of multiple male and female adaptor, usually a group of three to seven v rings, used for low or high pressure applications with Single or Double acting cylinder.

JST FHP series is  made of a helical wound spring and a polymer jacket, which is mainly used for piston.

Pumpdown plugs separate cement from the displacement fluid during liner cementing operations.

S Seals are well suited for sealing wellheads, connectors, downhole tools, high pressure valves and other demanding oil and gas applications. The non-extrusion springs can be fabricated from different metals.The S seal is made of spring and rubber material could be NBR, HNBR, FKM ect.

T-seals are three piece seals with an elastomeric lip and hard plastic anti-extrusion rings, it is proved to be of long time service. The standard design will fit into an o-ring gland and can be machined or net moulded.

FFKM O-rings provide the highest temperature (up to 620 ° F) and most common chemical resistance among all rubber O-ring and gasket materials.

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.

ID Face Seals for gate valves are spring-loaded, pressure-energized lip seal that improve gate and seat service life.
