Parker’s casing and tubing hanger flange seals are manufactured in sizes to suit specific applications and operating conditions, and may be split for in-situ assembly. The rectangular seal cross-section is compressed axially to generate a radial sealing force against the casing or tubing. The sealing element can be made from elastomer or may be an elastomer with anti-extrusion features molded into the elastomer. These anti-extrusion features include fabric, steel mesh, springs, and solid PEEK or PTFE rings.
The seals are available in NBR, HNBR, FKM and Aflas materials certified to API, ISO, Norsok, TOTAL and NACE standards.

Product benefits:
• Pressure resistance up to 20,000 psi
• Temperature resistance up to 400 °F (200 °C)
