PTFE guide and wear strips

PTFE guide and 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.

The advantages are the following:

enhanced compressive strength

enhanced thermal conductivity

reduced thermal expansion

reduced wear factor
