PU Polyurethane O-rings

I. Core Performance (Advantages of Polyurethane (PU) Material)

1. Ultra-high Wear Resistance
PU polyurethane exhibits significantly higher wear resistance than nitrile rubber and other rubber seals, with extremely low friction loss. Suitable for reciprocating motion and frequent compression friction conditions, it is resistant to cracking and chipping even after long-term use.

2. High Pressure Resistance and Resistance to Compression Deformation
High mechanical strength and a wide hardness range, it possesses strong resistance to permanent compression deformation. It will not rupture or bulge in high-pressure hydraulic equipment, making it suitable for hydraulic cylinders and high-pressure oil circuits.

3. Oil and Media Resistance
Good compatibility with hydraulic oil, lubricating oil, and engine oil; it is not easily swollen or softened; it is not easily corroded by grease, significantly extending its service life.

4. High Elasticity and Tear Resistance
High toughness and good tensile resilience; it is not easily torn even under pressure from sharp edges; it is more resistant to cut damage than ordinary rubber.

5. Made from Pure New Materials
No recycled waste materials are mixed in; the material is uniform, free of impurities and pores, ensuring stable sealing and preventing oil leakage.

New, pure polyurethane O-rings, wear-resistant and high-pressure resistant PU polyurethane O-rings, available in various colors.

Product Core Features: 1. Raw Material Advantage: Made with brand new pure polyurethane, rejecting recycled waste materials. Many low-priced sealing rings on the market contain recycled materials, making them prone to aging, air leaks, and oil leaks. This pure PU material is dense and non-porous, doubling its durability. 2. Dual Core Advantages of Wear Resistance and High Pressure Resistance: Balancing wear resistance and pressure resistance, this product is suitable for high-pressure hydraulic equipment, extending its lifespan by 3-5 times in wear-resistant scenarios. 3. Complete Specifications and Multiple Colors: Various outer diameters/wire diameters are in stock. The colorful packaging facilitates quick sorting, making factory maintenance and equipment installation more efficient. 4. Sales Proof: 1000+ units sold. Widely used in industrial scenarios, suitable for machine tools, hydraulic, and pneumatic equipment. High market acceptance, meeting most common hydraulic sealing needs. Universal O-ring Structure, Simple Replacement: Standard O-ring size, directly replacing old rubber rings without equipment modifications, upgrading the sealing solution at zero cost.
