Spring energized inside face seals apply spring force to press the sealing lip against an internal face. This design ensures axial sealing under pressure or vacuum. Made from materials like PTFE or PEEK, spring energized inside face seals resist chemicals, wear, and temperature changes. They are used in valves, static joints, and low-speed rotary systems, especially in aerospace, chemical, and cryogenic applications. These seals offer reliable, low-leakage performance in tight installation spaces.
