Spring Energized Outside Face Seals

Spring energized outside face seals use a spring-loaded sealing lip to press outward against a housing face. This ensures tight axial sealing under pressure or vacuum. Made from PTFE, PEEK, or other high-performance materials, spring energized outside face seals resist chemicals, wear, and extreme temperatures. They are used in static joints, valve bodies, and flanged connections in aerospace, chemical, and industrial systems. These seals offer long-lasting performance in tight or critical sealing areas.

Face Seals are typically used in static sealing applications. Outside Face Seals are often used to keep environmental media out of an exposed joint, hinge point, or pipe fitting. A PTFE Face Seal offers advantages over traditional O-Rings in terms of pressure handling, chemical compatibility, and operating temperature range. Use in cyrogenic applications is common.
