What's New


Trelleborg Sealing Solutions launched a metal end cap seal engineered for high-temperature, high-pressure (HTHP) wellhead, tubing and casing hanger sealing environments, which combines the pressure and extrusion resistance of a metal-to-metal bonded component with the flexibility of an elastomer.

The elastomer-to-metal bonded sealing elements provide the high level of extrusion resistance necessary for high pressure and temperature casing and tubing hanger applications. Optimal stress distribution throughout the elastomer body is modeled through finite element analysis (FEA) to ensure appropriate design standards are applied to each customer’s application. The mechanical end cap seal can withstand pressures up to 15,000 psi and temperatures up to 350° F in static applications. The seal materials are certified to NORSOK, NACE, API and Total standards.
