ChemResist Seals spring-energized PTFE seals are engineered for demanding sealing applications where conventional elastomeric seals may not provide the required combination of low friction, temperature resistance, pressure capability, chemical resistance, and long-term reliability.
Our spring-energized seals combine a high-performance PTFE or engineered polymer sealing jacket with a corrosion-resistant metal spring energizer. The spring maintains continuous sealing contact, while system pressure can further enhance the sealing force. This design makes spring-energized seals an excellent solution for challenging applications involving aggressive chemicals, extreme temperatures, high pressures, vacuum, and demanding dynamic motion.
ChemResist Seals designs and manufactures metric and inch-size spring-energized PTFE seals for a wide range of sealing configurations, including:
High-performance sealing solutions engineered for extreme temperatures, aggressive chemicals, high pressure, vacuum and demanding dynamic applications.
Spring-energized PTFE seals offer significant performance advantages where conventional elastomeric seals are limited.
ChemResist spring-energized seals combine advanced PTFE and engineered polymer materials with precision spring energizers to deliver reliable sealing performance across demanding operating environments.
Depending on the selected sealing material and spring configuration, ChemResist seals can operate from approximately -200°C to +260°C (-328°F to +500°F).
PTFE and high-performance polymer compounds provide excellent resistance to chemicals, corrosive fluids, solvents, gases and aggressive media.
The low-friction characteristics of PTFE-based sealing materials help minimize breakaway friction, running friction and wear, particularly in dynamic reciprocating and rotary applications.
Selected ChemResist seal materials can provide reliable sealing performance in applications where lubrication is limited or intermittent, subject to application conditions and material selection.
Standard designs can handle approximately 3,000 psi (210 bar), while special designs can be engineered for pressures up to 20,000 psi (1,380 bar).
The continuous loading provided by the spring energizer makes spring-energized PTFE seals suitable for a variety of vacuum and low-pressure sealing applications.
Engineered around the complete sealing system
The performance of a spring-energized seal depends on much more than the sealing material. ChemResist Seals evaluates the complete sealing system to develop the appropriate seal design for the application.
Our engineering team combines PTFE formulations, filled PTFE compounds, high-performance polymers, spring configurations and proprietary seal geometries to develop solutions for demanding sealing environments.
Spring energized seals are designed for demanding linear, reciprocating and static sealing applications. Their robust spring configuration provides continuous lip loading and is particularly suitable for applications requiring high chemical resistance, low friction and broad temperature capability.
Pressure:
Up to approximately 20,000 psi (700 bar) depending on seal design, installation clearance, material and application conditions.
For applications above 3,000 psi (210 bar), application-specific engineering review is recommended. Pressure capability may be increased through appropriate seal geometry and controlled hardware clearances.
Linear Surface Speed:
Up to approximately 10 m/s (33 ft/s) depending on seal design and operating conditions.
Rotary Surface Speed: Up to approximately 6 m/s (20 ft/s) depending on seal configuration, shaft conditions and application parameters.
Temperature:
Approximately -200°C to +260°C (-328°F to +500°F) depending on the selected sealing material and spring configuration.
ChemResist Seals offers spring-energized sealing solutions using a broad range of PTFE and high-performance polymer materials
Material selection is based on the actual fluid, temperature, pressure, surface speed, shaft or bore condition, extrusion gap and required service life.
