PTFE wear strips
PTFE wear strips are designed to perform the same function as a wear ring. Wear strip helps to keep the piston centered, which allows for even wear and pressure distribution on the seals. This is an excellent product for individuals who need custom sizes of wear rings. Wear strip can help to cut down on inventory and machining costs. Our standard wear strip material is bronze filled PTFE, other formulas pls contact us directly.
Fillers blended with PTFE allow to improve some basic physical properties of virgin polymers.
enhanced compressive strength
enhanced thermal conductivity
reduced thermal expansion
reduced wear factor
