Washers with Resistance to Weathering for Truck PTFE Ring Gaskets

PTFE parts

PolyTetraFluoroEthylene is a fluorocarbon-based polymer and is commonly abbreviated PTFE.

It offers high chemical resistance, low and high temperature capability, resistance to weathering, low friction, electrical and thermal insulation.

PTFE's mechanical properties are low compared to other plastics

but its mechanical properties can be enhanced by adding fillers such as glass fibers, carbon, graphite, molybdenum disulphide, and bronze.

PTFE O-RINGS

PTFE is a superior O-Ring material not affected by most chemicals. It can be used at temperatures up to 500°F (260°C). It has the lowest coefficient of friction of any solid material. Lubrication is less critical and can sometimes be omitted.

O-rings can be made 100% from PTFE or elastomers silicone or nitrile can be coated in a PTFE sheath for added chemical resistance while maintaining maximum flexibility.

Application:

1. low break-out and low friction hydraulic cylinder
2. low friction and no stick-slip pneumatic cyclinder
3. Plunger
4. Cyclinders in corrosive environment
5. Low friction cyclinders in high-temperature application
6. Cylinders for machine tool and construction equipment
7. Cylinders for press/ extrusion/injection molding equipment
8. Cylinders for precise control application
