Bonded seals for completion tools

High-pressure Rotary shaft seals are one bidirectional rotary seal which can bear both sides of pressure and alternating pressure. It is made with slip ring and o-ring/square ring.

JST's ESU series stem packings, also known as u packing, are designed to be placed between the stem and bonnet of Type FC gate valves. This stem packing gives you a reliable seal for superior performance.

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.

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.

Bidirectional high-pressure ball valve seat seal is a type of seat sealing that can withstand bidirectional pressure, with good low-temperature performance and airtightness, and is widely used in 6D ball valves.

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

The ID S seal is used for wellheads, downhole tools and surface pressure control equipment as a critial part.

ODU Piston seals are work to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
