External and Internal Spring Seals

The one-piece Spring (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 20 000 psi and temperatures of 177º C (350º F).

Our S-seal is made to perform in toughest situations, delivering reliable high-pressure static sealing. Our 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.

Our 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.
