S-Seal is a technologically advanced replacement for traditional three-piece T-Seals or O-Rings with back-ups. It is a compact, single piece seal design featuring an extrusion resistant elastomer with two anti-extrusion springs molded into the outer edges.
The combined seal can provide leak free sealing performance under extreme pressure. S-seal is very suitable for many chemical processing, chemical transportation and oil and gas applications, such as effective sealing applications that meet the following conditions:
The one-piece S-Seal eliminates installation problems that can occur when using multiple component seals. It can be stretched into place without splitting or compromising the non-extrusion elements of the seal.
S-seal sealing materials need to withstand pressures as high as 15 000 psi and temperatures of 149º C (300º F).
JST S-seal is made to perform in toughest situations, delivering reliable high-pressure static sealing. JST S-Seal elastomers are qualified to API 6A FF/HH (10% sour gas) and meet additional certifications which may include ISO 23936-2, NORSOK M-710.
JST S-seal is available in material NBR, HNBR, FKM with 2 integral anti-extrusion springs. Spring seals can be manufactured in a variety of standard or non-standard sizes, allowing them to be retrofitted into existing O-ring grooves.

Wellhead secondary pack off seal is used to seal the hanger to the wellhead.
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.
Lockdown screw seal is used mainly in geothermal applications, HNBR packing with stainless steel caps provide superior performance over metal pressure seals.
JST's metal end cap seal is elastomer bonded onto 2 steel caps. This provides high level of extrusion resistance.
The ID S seal is used for wellheads, downhole tools and surface pressure control equipment as a critial part.
Pack off seal or Secondary Seal Assemblies is installed in the lower seal area of the Casing Spool or Tubing Head.
P seal is constructed from an elastomer with back up rings for anti-extrusion. Energized by the injection of sealant, it is a static seal that is used to seal rough casing and tubing. Backup rings are available in Mesh Stainless Steel or Solid Carbon Steel.
The FS-seal is a relatively large cross section spring energized elastomer casing and tubing hanger seal for wellheads that always has the springs on the internal surface.
