Introduction
KAFLON T Series Special Spring PTFE Energized Seals are engineered for applications where standard spring configurations are insufficient to meet performance demands.
By incorporating customized spring designs and high-performance PTFE jackets, these seals deliver precise, stable sealing force under extreme operating conditions, including high pressure, vacuum, cryogenic temperatures, and aggressive chemical exposure.
The T Series is ideal for critical sealing interfaces requiring tailored load response, controlled friction, and long-term dimensional stability, making it a preferred solution for advanced industrial and OEM applications.

Key Design Characteristics
This makes the design particularly suitable for non-standard grooves and critical sealing zones.
Unlike conventional spring energized seals, the T Series utilizes special spring geometries—including customized helical, canted, or variable-load springs—to precisely match application-specific requirements such as:
01
Special Spring Configuration
- Uneven pressure distribution
- Bidirectional sealing
- Low contact force at startup
- High sealing force under pressure
02
PTFE-Based Sealing Jacket
Extremely low friction
Outstanding chemical resistance
Excellent wear and extrusion resistance
Dimensional stability over a wide temperature range
03
Custom-Engineered Performance
- Sealing force vs. friction
- Dynamic vs. static performance
- Pressure response vs. wear life

Materials & Configuration Options
Jacket Materials
- Virgin PTFE
- Glass-filled PTFE
- Carbon / graphite-filled PTFE
- Bronze-filled PTFE
- PEEK (for extreme load and temperature conditions)

Spring Materials
- Stainless Steel (standard industrial use)
- Elgiloy® (high fatigue resistance)
- Hastelloy® (corrosion and high-temperature resistance)

Material selection is customized based on media compatibility, pressure range, temperature, and motion type.
Range of Applications
The T Series Special Spring PTFE Energized Seals are designed for demanding environments where standard sealing solutions cannot deliver consistent performance.
Typical Applications Include
- High-pressure hydraulic and fluid power systems
- Chemical processing and reactor equipment
- Energy, oil & gas systems requiring customized sealing force
- Vacuum and ultra-clean process equipment
