Anping County Boli Hardware Wiremesh Products Factory (established 1998, annual export value US$5-10 million) proudly presents our UHMWPE Plastic Collar with a precise 2-inch inner diameter and 2.5-inch outer diameter, rated for 500 PSI working pressure. Engineered from ultra-high molecular weight polyethylene, this collar delivers exceptional wear resistance, low friction, and long service life, making it an ideal choice for pipe protection, spacer applications, and industrial wear parts. Whether you need a reliable bushing for hydraulic systems or a durable ring for conveyor rollers, our collar offers a cost-effective solution without compromising performance.
Our product stands out due to its superior abrasion resistance – UHMWPE is 10 times more wear-resistant than carbon steel and 4 times more than nylon. The collar’s tight dimensional tolerance (±0.5 mm) ensures a perfect fit, while its self-lubricating properties reduce maintenance needs. It is non-toxic, odorless, and resistant to chemicals, moisture, and UV radiation, enabling reliable operation in harsh environments.

Benefits to Your Application: This collar eliminates metal-to-metal contact, reduces noise, and prevents galling. Its lightweight nature (only 1/8 the weight of steel) simplifies handling and installation. The non-stick surface resists buildup of scale, sludge, or debris, making it perfect for slurry lines, water treatment, and food processing environments.
Frequently Asked Questions (FAQ)
- Q: Can this collar handle continuous 500 PSI pressure? A: Yes, the 500 PSI rating is the maximum static working pressure at room temperature. For dynamic or pulsating applications, we recommend a safety factor of 1.5-2.
- Q: Is it suitable for outdoor use? A: UHMWPE has excellent UV resistance, but prolonged direct sunlight may cause slight discoloration. For long-term outdoor exposure, consider black pigmented material.
- Q: What is the tolerance on the inner diameter? A: Standard tolerance is ±0.2 mm. If you require tighter fit, we can produce to ±0.1 mm upon request.
- Q: Can I get custom colors or sizes? A: Absolutely. We offer custom dimensions, colors (including RAL codes), and even add anti-static properties. Minimum order quantity may apply.
- Q: Is this product food-grade? A: Our UHMWPE is made from virgin resin that complies with FDA regulations for incidental food contact. Please inform us if you need a food-grade certificate.
- Q: How does it compare to nylon or acetal? A: UHMWPE has better wear resistance, lower moisture absorption, and higher impact strength than nylon or acetal. It is also more slippery and quieter in operation.
- Q: Do you provide samples? A: Yes, we offer free samples for evaluation (shipping cost may apply). Contact us with your requirements.
- Q: What is the lead time for bulk orders? A: Typically 10-15 working days for quantities up to 10,000 pieces. Larger orders may require 20-30 days.
