NBR Rubber Sealing Parts: Professional Solution for Oil-Resistant Industrial Scenarios
Nitrile rubber (NBR) is the most widely used oil-resistant rubber material in the machinery industry. It has excellent resistance to engine oil, hydraulic oil, gasoline, and diesel, and has good wear resistance and sealing stability. It is the core material of hydraulic system seals, pipeline gaskets, and automotive oil circuit accessories.
Many mechanical equipment failures are caused by oil leakage and seal aging. Choosing high-quality NBR rubber parts can effectively improve equipment stability and reduce maintenance costs. The following are the core performance parameters of our high-quality NBR products:
Parameter | Standard Value | Industrial Advantage |
|---|---|---|
Oil Swelling Rate | ≤3% (24h immersion test) | No volume deformation in long-term oil contact |
Working Temperature | -40℃ ~ 100℃ | Adapt to conventional mechanical operating temperature |
Tensile Strength | ≥10MPa | Strong wear resistance, not easy to break |
Hardness Range | 40A – 85A customizable | Meet soft buffer and hard sealing needs |
Compression Resilience | ≥90% | Long-term compression without permanent deformation |
We supply standard and customized NBR O-rings, flat gaskets, special-shaped sealing parts, and rubber buffer blocks. Products are widely used in hydraulic machinery, automotive engineering, agricultural equipment, and petroleum machinery, with stable sealing performance and long service life.
