PTFE Ring Gaskts with Resistance to Weathering in White O Ring

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.

The requirement for low coefficients of friction, less than .08, temperatures ranging from -300F to +550F, pressures in excess of 5000 psi, the need to seal a corrosive acid …..These are the typical kinds of factors that tell you that an elastomeric seal probably wont fit your application.

Seal Science PTFE or ® Seals and Seal Science Perflex perfluoroelastomer are often the answer. Possibly something as simple as a PTFE O-Ring, or a PTFE compound cap to protect the elastomer will do. Or maybe, spring energized PTFE U-Cups, like those in our Polyspring line might be needed. Many of the possible solutions can be found in our Polyking catalog. Whatever the appropriate choice may be, our PTFE engineers will be able to quickly offer you a recommendation and a quote.
