Spring Energized Seals
Energized PTFE seals offer extreme-temperature, high-pressure, chemically inert, static and dynamic
seals for the most demanding applications. Our thin, flexible PTFE sealing jacket, made resilient
by an internal energizing spring, applies a load to the sealing element at low pressures. As the
system pressure increases, the spring engages to create a highly efficient seal against the
mating surface. The spring provides permanent resilience to the seal jacket
and compensates for jacket wear, hardware misalignment or eccentricity.
- PTFE compounds with almost universal chemical compatibility
- Stainless steel springs for corrosion resistance
- Wide temperature range -400°F to +600°F
- Static and dynamic applications
- Vacuum to 60,000 psi
- Can run dry or lubricated
- Low friction seals
- Sizes up to 60" diameter
Applications:
Hydraulic Actuators, Aircraft Engines, Brake Systems, Chemical Pumps, Compressors,
Cryo Coolers, Food Processing Equipment, Mechanical Seals, Oil Field Equipment, etc.
Factors Influencing Seal Performance
Several factors effect seal performance and must be addressed in the design stage to ensure
maximum reliability of Tetralon® seals.
- Hardware Preparation: Surface Finish and Hardness
- Spring Energizer
- Polymer Jacket
- Operating Conditions
- Lubrication
- Frictional Considerations
- Spring Load vs. Deflection
- Extrusion Gap / Radial Clearance
