Compound

Nitrile (NBR)

The workhorse oil-resistant elastomer. Excellent resistance to petroleum oils, hydraulic fluids, greases and diesel, with good abrasion and compression-set behaviour at a modest cost.

Why specify NBR

  • Outstanding resistance to mineral oil, fuel and grease
  • Good tensile and abrasion resistance
  • Low compression set — holds sealing force over time
  • Food-grade compounds available for winery and dairy duty

Where it fails

Poor resistance to ozone, weathering and strong acids. Not suitable for brake fluid, ketones or continuous sunlight exposure — specify EPDM instead.

We would rather talk you out of the wrong compound than sell you a part that comes back in three months. If the duty is borderline, send the operating conditions and we will say so plainly.

Typical components in NBR

  • Oil seals and hydraulic seals
  • Pump and dosing diaphragms
  • Flange and ring gaskets
  • Winery impellers in food-grade compound

Send a drawing, a sample, or just a photo of the worn part.

We will identify the compound, quote the tooling and get a first sample to you. No drawing needed — a measured sketch or the old component is enough to start.
