Double-Layer PTFE Coated O-Ring Material Characteristics: Corrosion-resistant, High-temperature resistant, Wear-resistant
Coated O-Ring, also known as Fluorine-coated O-Ring or Coated O-Ring, is a sealing component composed of a relatively thick inner core made of materials like silicone rubber or fluorine rubber and a relatively thin outer coating of various materials such as PTFE/FEP/PFA. This product combines the elasticity and sealing properties of O-Ring rubber materials with the chemical resistance of materials like PTFE, FEP, and PFA, offering excellent sealing performance. Our company can customize various colors and shapes of coated O-rings based on drawings, samples, specifications, and materials provided by customers.


Main Features
Excellent chemical resistance, suitable for almost all chemical media, such as strong oxidizing and strong reducing solvents, with strong resistance to corrosion from strong acids and alkalis; wide applicable temperature range, from -200°C to +260°C; excellent compression resistance, greater than or equal to 30%; extremely low friction coefficient, only between 0.1~0.2; good anti-swelling property ≤0.1%; extremely high pressure resistance, up to 60Mpa; good sealing continuity, extending service life by more than 5 times.

Hardness Description:
The average hardness of coated O-rings made from different materials is as follows:
Hollow Silicone Rubber: 75-80
Solid Silicone Rubber: 85-90
Solid Fluorine Rubber: 90-95

Material Description
FEP and PFA coating materials are essentially very similar, but PFA material has better high-temperature resistance than FEP. The applicable temperature range for FEP is -60°C to 205°C, while for PFA it is -60°C to 260°C.
