Nitrile (NBR) — Solid
Solid nitrile rubber is the material of choice when oil, fuel, and hydrocarbon exposure are the primary sealing challenge — from industrial machinery and pumps through aerospace fuel systems and electrical transformer oil environments. Its acrylonitrile-butadiene chemistry provides excellent resistance to aliphatic fuels, oils, and greases across a service temperature range of -40°F to 250°F, and carries the qualification credential — AMS 3215 — required for continuous fuel system exposure in aerospace applications. H-O Products carries the full range of solid nitrile families, from commercial and FDA industrial grades through AMS 3215 aerospace fuel-resistant, transformer oil, bio-diesel, and cloth-inserted variants, and converts them to customer specification.
