1. Product Advantages
Forever Seals’ PTFE-based spring energized seals boast exceptional durability, thanks to high-quality PTFE material that resists corrosion, wear, and extreme temperatures (-200°C to 260°C). The integrated spring ensures consistent sealing force, eliminating leak risks even under high pressure (up to 50 MPa). Unlike standard seals, they require minimal maintenance, reducing downtime and operational costs for industrial users.
2. Working Principle
The seal combines a PTFE sealing element with a metal spring (stainless steel 316L optional). When installed, the spring exerts constant pressure on the PTFE lip, forcing it to adhere to the mating surface. As pressure increases, the fluid pressure further energizes the PTFE element, enhancing the seal tightness. This dual-energization design guarantees reliable sealing in dynamic and static applications.
