NBR (Nitrile Rubber)
Standard for oil resistance in general industrial and mechanical seals.
- Oil Resistance: Excellent resistance to petroleum-based oils and fuels
- Temperature Range: -30°C to +120°C continuous service
- Standard Compliance: ASTM D2000 BF, ISO 3601-1 Class B
The Engineering Advantage
NBR is the workhorse of industrial sealing — cost-effective yet highly capable in oil-rich environments. RubberQ's NBR compounds are specified for Hydraulic Systems and General Machinery Seals requiring reliable fluid containment.
Every NBR batch undergoes oil-immersion swell testing per ASTM D471, ensuring predictable dimensional stability in service.
