The Spring Energized PTFE filled with carbon seal is a spring- energized, pressure-assisted sealing device consisting of a PTFE filled with carbon partially encapsulating a corrosion-resistant V shape metal spring energizer.
carbon fiber is a category of composite materials derived from carbon - based sources, renowned for their exceptional strength, lightweight nature, and versatility across various industries and applications.
PTFE filled with carbon material has exceptional strength and lightweight nature,electrical conductivity and thermal stability,chemical resistance.Due to their ability to enhance strength, conductivity, and performance in diverse applications.
FUNCTION
Sealing of piston rods
Use as swivel seal
Suitable for high pressures and vacuum due to active preloading of the sealing lip
Use with one-sided pressure load
Use with high tolerances
V-spring for gap bridging
Advantages
