High Temperature Seals
High Temp Sealing Solutions for Harsh Environments
High-temperature applications demand seals that can withstand extreme heat, pressure, and aggressive chemicals without degradation. At Performance Sealing Inc. (PSI), we specialize in high-performance high-temperature seals designed to maintain integrity and durability in aerospace, energy, industrial, and automotive applications.
High-Temperature Seal Materials for Maximum Performance
PSI’s Duron® high-temperature sealing materials are engineered for long-term thermal stability, chemical resistance, and low friction performance. Our most advanced materials include:
- Duron® 6 – A carbon-graphite-filled PTFE blend providing superior sealing performance from -250°F to 600°F.
- PEEK (Polyether Ether Ketone) – A high-strength polymer offering exceptional heat and chemical resistance.
- Metal-reinforced high-temperature seals – Designed for extreme conditions where added structural integrity is required.
These materials ensure leak-free performance and resistance to heat-induced breakdown, making them ideal for demanding high-temperature sealing applications.
Types of High-Temperature Seals We Offer
We manufacture a complete range of high-temperature sealing solutions, including:
- High-temperature rotary shaft seals – Designed for motors, pumps, and industrial machinery
- High-temperature hydraulic seals – For pressurized fluid systems operating at elevated temperatures
- Spring-energized high-temperature seals – Ideal for dynamic and static sealing in extreme environments
- Vacuum and pressure seals – Used in semiconductor, aerospace, and high-heat industrial applications
- High-temperature oil seals – Ensuring leak-free performance in high-friction conditions
