Parker’s S-Seal is a single-piece seal with anti-extrusion features molded into the elastomer sealing element. The bi-directional seals can be used for rod or piston applications and are specifically engineered for use in down-hole, subsea and wellhead equipment where exposure to well bore fluids at elevated pressures and temperatures demand a robust sealing solution. The S-Seal product series is available to retrofit in BS-1806 grooves or can be custom-designed for specific applications and grooves.

Product benefits:
• Pressure resistance up to 20,000 psi
• Temperature resistance up to 600 °F (320 °C)
• Easier installation and maintenance due to single-piece design
• Bi-directional sealing
• Retrofit in BS-1806 grooves
• Custom designs available for specific applications
• Size range from 1/2" (12.7 mm) to 60" (1.5 m) in diameter
• Available for both static and dynamic applications
• Materials certified to API 6A FF/HH and Norsok M710 (ISO 23936-2)
• Available with stainless steel, Inconel and PEEK springs
• Double sealing bead variant available for sealing against poor surface finishes
