Spring Energized Seals

Internal Face Seals are expertly designed for static sealing applications, providing reliable containment of pressure within vessels. These seals are commonly used as lid seals or in pipe flange fittings, where maintaining a tight seal is critical.


Internal Face Seals are particularly advantageous in demanding environments. Constructed from PTFE (Teflon), these seals offer superior performance compared to traditional O-Rings. Their enhanced pressure handling capabilities make them ideal for high-pressure applications, while their excellent chemical compatibility ensures durability in aggressive environments. 


Additionally, PTFE Face Seals operate efficiently across a wide temperature range, making them suitable for both high-temperature and cryogenic applications.


The use of PTFE in Internal Face Seals brings several benefits. PTFE’s low friction properties reduce wear, extending the seal's lifespan and maintaining its integrity over time. This makes PTFE Face Seals a reliable choice for static sealing needs, especially in applications where long-term performance is essential.


Internal Face Seals are ideal for use in cryogenic applications, where they must maintain a tight seal despite extremely low temperatures. Their ability to handle high pressures and resist chemical attacks makes them suitable for use in pipe flange fittings and other critical sealing scenarios.


These seals provide a dependable barrier in static sealing applications, ensuring that pressure is contained effectively within vessels and fittings. The superior material properties of PTFE make these seals a versatile and resilient option for a wide range of industrial applications.
