The 216391-G Secondary Seal is manufactured from premium-grade elastomeric materials formulated for explosive decompression resistance. Its reinforced design is optimized to maintain a secure interference fit even under extreme temperature fluctuations. By providing a secondary layer of protection, it significantly enhances the safety and reliability of wellhead and Christmas tree assemblies. The seal's specialized geometry reduces mechanical wear on the stem, prolonging the service life of the valve. It is essential for operators seeking to minimize maintenance intervals in harsh environments.
