English
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.

50HNBR S seal for downhole application
Wellhead is a key component of oil and gas infrastructure. Wellhead sealing materials need to withstand high pressure and high temperature.
S-seal is a compact one-piece seal design with anti extrusion elastomer with two molded anti extrusion springs at the outer edge. Its unique design integrates two non extrusion devices and a sealing element into an overall structure to provide two-way sealing. At the same time, combined with a simple symmetrical contour non extrusion device, headless coil springs are used on both sides of the seal, allowing a large extrusion gap to be bridged under high pressure. Non extruded equipment (when made of the following materials) limits metal seals to static applications. S seal is a preferred design which attack by oilfield media where an O ring cannot survive the maintenance-free life cycle of the equipment.

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.
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.
The ID S seal is used for wellheads, downhole tools and surface pressure control equipment as a critial part.
Perfluoroelastomer (FFKM) O-rings have carbon fluorine bonds, making them one of the most thermally stable, oxidative stable, and chemically stable fluorinated polymers.
Hammer union seals are used for hammer joint type pipe connections to establish flow lines and prevent leakage.
FFKM O-rings provide the highest temperature (up to 620 ° F) and most common chemical resistance among all rubber O-ring and gasket materials.
Lockdown screw seal is used mainly in geothermal applications, HNBR packing with stainless steel caps provide superior performance over metal pressure seals.
The BVR series is made of a canted level spring and a polymer jacket, which is mainly used as a seat seal.
