O-rings and oil seals are the most fundamental yet critical sealing components for mechanical equipment. Even high-end machinery can suffer from leakage, shutdown, and premature wear due to improperly selected seals. The key to long service life and stable equipment operation is not choosing the most expensive seal, but matching the right seal material and structure according to actual working conditions.

Spring energized seals consist of PTFE shell and stainless steel spring. With continuous spring preload to compensate wear automatically, they resist extreme temperature, strong acid & alkali and various organic solvents. Suitable for vacuum, high pressure and cryogenic working conditions, widely used in new energy, petrochemical, pharmaceutical, aerospace and semiconductor for static & dynamic sealing. Custom materials and sizes are available at FOREVER SEALS.
