PTFE Seals-type WA
PTFE wipers are mainly used where wipers of other materials would fail because of the particular operating conditions involved. Their function lies in preventing foreign particles or fluids from preventing into the sealing area, thereby protecting the seals, guides and bearings behind the wipers from wear and damage.
Sealing pressure on PTFE wiper lip is usually energized by an elastic O-ring. The standard material combination is bronze filled PTFE and NBR. This is mainly utilized in hydraulic and pneumatic application.
The function of wiper rings is to prevent dust, dirt and foreign material from immigrating into sealing rods and plungers. It features minimal break-out and dynamic friction to guarantee no stick-slip. PTFE compound enhances wear resistance to retain anticipated performance over a long period of time.
