PTFE O Rings for Automotive Plumbing and Heat Resistant Sealing

Our PTFE O Rings are manufactured from high-quality polytetrafluoroethylene (PTFE), a durable fluoroplastic known for its excellent chemical resistance, low friction, and wide operating temperature range.

These PTFE rubber-free sealsoffer outstanding resistance to acids, alkalis, solvents, and many aggressive chemicals, making them suitable for demanding industrial sealing applications. With a temperature resistance ranging from -250°C to +250°C, depending on material grade and operating conditions, PTFE sealing rings are ideal for static flange sealing in chemical processing equipment, automotive repair systems, plumbing connections, faucets, and air or gas fittings. Unlike conventional rubber O rings, solid PTFE O-rings have limited elasticity and are primarily designed for static sealing in properly designed grooves.

As a professional PTFE O-ring manufacturer and supplier, we offer custom PTFE seals, chemical-resistant O-rings, high-temperature sealing rings, and precision PTFE components in various sizes and specifications.

Correct measure the O-Rings Size

1.Do not measure O-rings with a ruler.

2.Use a caliper to accurately get ID, OD and cross-section CS.

3. Rubber O-rings deform easily. Accurate measurement ensures proper fit and prevents leakage.

Rubber Seal O-Rings Price Compare

PTFE O rings offer excellent chemical resistance, a wide temperature range, low friction, and reliable static sealing performance. They provide a cost effective sealing solution compared with FEP and FFKM materials for various industrial applications.

PTFE O-Rings Advantages

Manufactured with attention to surface finish, dimensional accuracy, and cross-sectional consistency. Products are inspected for surface defects such as pores, burrs, and cracks according to applicable quality requirements.

Superior chemical resistant PTFE O-rings, resistant to acids, alkalis and solvents for stable sealing in corrosive working conditions.

PTFE O-rings feature excellent high and low temperature resistance, stable performance from -100°F up to 500°F, to keep your equipment running smoothly.

Available in standard sizes and selected stock specifications. Custom manufacturing is available for special dimensions, hardness requirements, and bulk orders.

PTFE,FEP AND FFKM O Rings Comparison

PTFE O-rings offer excellent chemical resistance, a wide temperature range, and low friction, making them ideal for static sealing applications. FEP-encapsulated O-rings combine chemical resistance with an elastic core, while FFKM O-rings provide excellent elasticity and high-temperature performance. The best material depends on operating temperature, sealing requirements, chemical exposure, and budget.

PTFE O-Ring Installation Guide

PTFE O-rings are designed for static sealing in closed grooves, not for dynamic piston or rod seal applications. The ring must be installed without stretching over components, so the groove should be designed for easy insertion, often as a split or open groove. Controlled compression is important to minimize cold flow and maintain stable sealing performance. Proper groove dimensions and tolerances should be confirmed through O-ring groove calculation and tolerance analysis.

Application for PTFE O-Rings

PTFE O-rings are suitable for a wide range of industrial sealing applications, including mills, crushers, and grinders; pumps; stirring and agitator systems; transmissions and gearboxes; rotary or screw-type air compressors; machining tools; centrifuges; and blower systems. Overall, they can be used in industrial processes such as material crushing and grinding, fluid transfer, mixing and agitation, power transmission, air compression, machining, centrifugal separation, and ventilation/blowing, where they provide reliable sealing performance.
