CH-PG2000+Hsp Spring Energized Seal
Suitable for Extreme Sealing in High Temperature, High Pressure, and Complex Operating Conditions
The CH-PG2000+Hsp Spring Energized Seal is a high-performance sealing solution designed for demanding industrial environments where conventional elastomer seals may fail. Featuring a modified PTFE jacket combined with a corrosion-resistant 316 stainless steel spring, this seal delivers reliable performance under high temperatures, pressure fluctuations, and challenging media conditions.
Its unique extended-tail design helps prevent seal extrusion caused by excessive groove clearance, providing an effect similar to a retaining ring. This makes it particularly suitable for dynamic shaft sealing and piston sealing applications operating at pressures up to 40 MPa.
