PTFE Ring

PTFE 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 seals have 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. As one of the professional ptfe ring manufacturers and ptfe o ring suppliers, Xinrui can custom special size of PTFE seal rings according customer requirement.

PTFE Ring Features

Temperature resistance: ptfe seal ring 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, ptfe o ring is easier to remove those resin, dopes, oil and other sticky things.

Anti-aging, weathering resistance.

PTFE seal ring has 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.
