Product Name: Carbon Filled PTFE Spring Energized Valve Seal

Typical applications of Spring energized PTFE Seals are in oil and gas valve, defence and aerospace, low temperature application, medical equipment, and sealing systems that demand extreme chemical resistant. We can also specially design it to be used for sterilization, clean-rooms and ultra-high vacuum purposes.

The spring energized PTFE Seals we manufacture are recommended for sealing in extreme operating conditions of temperature, speed and chemical. It consists of a PTFE U-shaped profile ring energized by a finger spring. The finger spring can be a stainless steel V-spring or canted coil spring. The Spring energized PTFE Seal design is such that the lip will be pushed against the sealing surface at low pressure and also at high pressure. We can make this type of PTFE seal using pure PTFE, PTFE Carbon, PTFE Graphite, PTFE Bronze or PTFE Glass. The features of these PTFE seals are :

very low friction and will not seize after long period of unuse when installed in a hydraulic system

chemical resistant

wide operating temperature range

wide operating pressure from vacuum up to 200 bar

operating speed up to 10 m/s

can be used to seal gases

can replace O-rings
