Teflon Spring Seal
Product Overview
KAFLON® Teflon Spring Energized Seals are advanced sealing solutions designed for extreme operating conditions where conventional elastomer seals cannot perform reliably.
These seals consist of a PTFE (Teflon) jacket combined with a corrosion-resistant metal spring energizer, providing consistent sealing force even under low pressure, high temperature, vacuum, and chemically aggressive environments.
Key Features & Benefits
Extremely low friction coefficient
Excellent chemical resistance (almost all media)
Wide temperature range
Suitable for vacuum and cryogenic conditions
Stable sealing under low pressure conditions
No elastomer degradation issues
