O-Ring Technical requirements:
Appearance meets GB/T3452.2-2007 Material meets HG/T2579-2008 Size meets GB/T3452.1-2005
In addition, all our products are ROHS and REACH Compliant (we mainly export products to USA and Europe market).
O-Ring Features:
1. Good sealing solution, long service life.
2. Easy installation reduces risk.
3. Working in various medium based on different elastomer material.
A PU O-ring is a type of sealing ring made from Polyurethane (PU), a versatile elastomer known for its exceptional mechanical properties. O-rings are circular sealing components designed to prevent the leakage of fluids (liquids or gases) in various industrial applications. PU O-rings are widely used due to their unique combination of durability, flexibility, and resistance to wear and chemicals.
Excellent Wear Resistance:
Polyurethane is highly resistant to abrasion, making PU O-rings ideal for high-friction or high-wear environments.
Good Elasticity and Compression Set Resistance:
PU O-rings can maintain their shape and sealing ability even after prolonged compression, ensuring reliable performance.
Oil and Chemical Resistance:
PU O-rings perform well in environments exposed to oils, greases, and many chemicals, making them suitable for hydraulic and pneumatic systems.
High Tensile Strength and Tear Resistance:
Polyurethane has high mechanical strength, allowing PU O-rings to withstand high-pressure applications.
Temperature Range:
PU O-rings typically operate within a temperature range of -30°C to +80°C, though specialized formulations can extend this range.
| Property | PU O-Rings | NBR O-Rings | Silicone O-Rings | FKM O-Rings |
|---|---|---|---|---|
| Wear Resistance | Excellent | Moderate | Poor | Moderate |
| Oil Resistance | Excellent | Excellent | Poor | Excellent |
| Temperature Range | Moderate (-30°C to +80°C) | Moderate (-20°C to +120°C) | Excellent (-60°C to +200°C) | Excellent (-20°C to +200°C) |
| Elasticity | Excellent | Good | Excellent | Good |
| Cost | Moderate | Low | High | High |
Choose PU O-rings for applications involving high wear, high pressure, or exposure to oils and greases.
For high-temperature or harsh chemical environments, consider alternative materials like FKM or silicone.
Limited resistance to high temperatures (typically up to 80°C).
May degrade in strong acids, bases, or humid environments.
Resistance to oils, greases, and many chemicals.
High load-bearing capacity and durability.
Superior wear resistance, leading to longer service life.
Excellent sealing performance due to high elasticity.
PU O-rings are used in a wide range of industries and applications, including:
Hydraulic and Pneumatic Systems:
Sealing cylinders, valves, and pumps.
Automotive Industry:
Used in engines, transmissions, and fuel systems.
Heavy Machinery:
Sealing components in construction equipment like excavators and bulldozers.
Industrial Equipment:
Used in compressors, pipelines, and fluid handling systems.
