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.
