                                   PTFE O Rings

O-rings are one of the most common sealing solutions. Teflon PTFE o-rings are known for high heat resistance, high resistance to chemical agents and solvents, anti-adhesiveness, dielectric properties, low friction coefficient, and non-toxicity.

PTFE offers many distinct advantages over elastomers. These advantages include corrosion resistance, massive temperature range capabilities, excellent electrical properties and an almost unlimited shelf life.

The PTFE O-Rings are widely used in applications which require a chemically resistant and non-compressible material. PTFE is a plastic that offers high chemical resistance, low and high temperature capability, resistance to weathering, low friction, electrical and thermal insulation, and "slipperiness".

The PTFE O-rings or Teflon O-rings have excellent thermal and electrical insulation properties and a low coefficient of friction.

HONGDA supplies O-rings in a wide range of sizes and different materials, such as PTFE, TFM, filled PTFE, PCTFE，which make them appropriate for a wide variety of operating conditions and applications.

PTFE Teflon O-rings are ring-shaped seals made from the chemical polymer polytetrafluoroethylene, or PTFE for short. PTFE O-rings work like any O-ring to seal two or more parts at the interface.
