Oil-Resistant NBR Rubber O-Ring Seals Nitrile O-Rings for Gearbox Pipeline
1. Material and Color NBR nitrile rubber O-rings are made from qualified raw materials, available in black or other colors, with a dense cross-section. They offer oil and water resistance, resist swelling and deformation, and provide reliable sealing.
2. Temperature Adaptability With a temperature range of -40°C to 120°C, they maintain good elasticity at low temperatures and resist hardening and cracking at high temperatures, ensuring stable sealing across a wide temperature range to meet continuous operation needs.
3. Performance Parameters Compression rate approx. 20%, fill rate approx. 75%, tolerance ±0.05. Uniform stress distribution ensures durable sealing. Low cost and high cost-effectiveness make them suitable for bulk applications.
4. Application Scenarios With oil resistance, water resistance, and wide temperature adaptability, they are widely used for sealing in automotive engines, gearboxes, fuel systems, and pipeline equipment—economical and practical.
5. Service Life NBR nitrile rubber O-rings have a normal service life of 5 to 10 years, with the actual lifespan affected by temperature, media, and operating conditions.
For sealing requirements in fuel systems and pipeline equipment, we recommend a combined solution of fuel-resistant nitrile seals and pressure-resistant rubber gaskets. The NBR rubber gasket has a rated temperature range of -30°C to 120°C, offers oil and water resistance, and resists swelling and deformation. With a compression rate of approximately 20%, a fill rate of about 75%, an outer diameter tolerance of ±0.1mm, and a cord diameter tolerance of ±0.05mm, it provides durable and reliable sealing. The solution is suitable for automotive engines, fuel lines, gearboxes, and chemical pipelines, balancing pressure resistance and cost-effectiveness. It is a high-value NBR rubber sealing solution for the machinery and pipeline industries.
