Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer with over two decades of experience in producing precision sealing components. Our PTFE Plastic Collar is engineered to deliver reliable performance in extreme temperature environments ranging from -50°C to 260°C, making it the ideal choice for demanding industrial sealing applications. With annual export value exceeding US$5 million and serving markets across North America, Europe, Asia, and Oceania, we bring global quality standards to every product we manufacture.
The PTFE (Polytetrafluoroethylene) collar is designed for high-temperature resistance, chemical inertness, and low friction. It provides excellent sealing in pumps, valves, compressors, and other rotating or static equipment. Our collars are manufactured using advanced compression molding and sintering techniques, ensuring consistent density and dimensional accuracy.
Key Features & Technical Specifications
- Wide Temperature Range: Operates continuously from -50°C to +260°C, with intermittent peaks up to 300°C (check datasheet for specific conditions).
- Chemical Resistance: Inert to almost all chemicals, including strong acids, alkalis, and organic solvents – ideal for harsh media.
- Low Friction Coefficient: Self-lubricating properties reduce wear on mating surfaces, extending equipment life.
- Non-Stick Surface: Prevents adhesion of sticky materials, reducing maintenance downtime.
- Electrical Insulation: Excellent dielectric properties – suitable for electrical and electronic applications.
- Customizable Dimensions: Available in a wide range of inner diameters, outer diameters, and thicknesses to fit your specific sealing groove.
- RoHS & REACH Compliance: Manufactured with environmentally friendly materials (certificates available upon request).

Frequently Asked Questions
-
Q: What is the maximum operating temperature for this PTFE collar?
A: The continuous operating temperature range is -50°C to 260°C. For short-term intermittent exposure, temperatures up to 300°C may be acceptable, but we recommend consulting our engineers for your specific application. -
Q: Can the collar be used in food contact applications?
A: Yes, virgin PTFE is FDA-compliant for food contact. We can provide material certifications upon request. Please specify if you need food-grade documentation. -
Q: Do you offer custom sizes or shapes?
A: Absolutely. We can manufacture collars with custom inner diameter, outer diameter, thickness, and even non-circular profiles. Minimum order quantities may apply for non-standard sizes. -
Q: What is the typical lead time?
A: For standard sizes, lead time is 7–15 working days. Custom orders typically require 15–30 working days depending on complexity. We can expedite for urgent requests. -
Q: Is this product suitable for high-pressure sealing?
A: PTFE collars are primarily used for static or low-pressure dynamic sealing. For high-pressure applications, we can recommend reinforced or filled PTFE grades or custom designs with backup rings. Please provide your pressure and environment details. -
Q: What packing options are available?
A: Standard packing includes poly bags then cartons or wooden pallets. For export, we use moisture-proof packaging. Custom packaging (blister, individual barcode, etc.) is available upon request. -
Q: Do you provide samples for testing?
A: Yes, we can provide free samples for standard sizes; the buyer pays shipping. Custom samples may incur a small mold or tooling fee. Contact us to discuss your testing needs. -
Q: How do I ensure the correct size for my application?
A: Provide the shaft diameter, housing bore, and groove dimensions (width and depth). Our technical team can help you select the appropriate collar size and recommend tolerances.
