PTFE Ring

PTFE O Ring
PTFE sealing products not only can seal oil fluid, can also seal water a class
of fluids, including strong acid, strong alkali, strong corrosion strong
chemical fluids and a variety of solvents, it can also seal a variety of gases,
to adapt to dry friction occasions. None of these rubber seals can be achieved.

PTFE seal has simple structure, shape and size can be interchangeable with
rubber seal, easy installation and maintenance.

Normally, PTFE ring and PTFE gasket can be together called PTFE sealing
product, usually, the difference is the thickness above 5mm, it can be called
PTFE gasket, below 5mm, it can be called PTFE ring. The special size can be
customized according customer requirement.

Features of PTFE Ring
Temperature resistance: It is able to work stably between -180°C to +260°C.

Excellent chemical corrosion resistance: Applicable medium includes oil, acid
solution and almost all chemical materials.

Excellent non-sticky property: With low friction coefficient it easier to
remove those resin, dopes, oil and other sticky things.

Anti-aging, weathering resistance.

Excellent insulation property.

Filled material: Filled PTFE products has more outstanding performance by
adding filler such as carbon, graphite, bronze, glass fiber, carbon fiber,
MOS2, PEEK, PI, POB BaSO₄, SiO₂, glass bead, polyamide.
