S Seals

S Seals

One piece design for easier installation

Traditional sealing solutions cannot provide adequate safety at elevated application levels. The integrated spiral spring in the S seal ensures high pressure resilience, excellent resistance to rolling and bunching, and simple fitting. A standard range designed to suit AS668B O-Ring housings is available to be retrofitted into original O-Ring grooves in three standard lengths.

Freudenberg Oil & Gas Technologies Spring Seals are mostly used in stab and static applications for high cyclic pressure and temperature peaks of up to 15,000 psi and 210° C (410° F) or higher, depending on housing design and material choice. Used for many oil and gas applications like within wellheads, downhole tools and surface pressure control equipment, Freudenberg Oil & Gas Technologies’ Spring Seals are supplied in a wide range of materials. Custom sized designs are also available.

Freudenberg Oil & Gas Technologies’ 400 series long axial groove length 5.00” and 13.00” S Seals were successfully pressure/temperature cycle tested in accordance with ISO 10423, Made in our proprietary Gazguard material, the seals were qualified to 10,000 psi from 0°F (-18°C) to 250°F (121°C). Test certification is available for download to registered users.
