Buna N sheet is a type of nitrile rubber product known for its reliable performance in demanding industrial environments. It offers consistent oil resistance and mechanical strength, making it a preferred material for gasket fabrication. When shaped into a buna N gasket sheet, it performs exceptionally well under compression, helping to maintain tight seals even in systems that experience fluctuating temperatures and pressures.
The sheet resists degradation from petroleum-based fluids, diesel, greases, and certain solvents, making it useful in engine compartments, hydraulic systems, and fuel-handling operations. With its flexible surface and moderate elongation properties, the buna N sheet adapts well to curved surfaces and irregular profiles.
Supplied in uniform thickness and consistent density, the material supports applications in automotive maintenance, refinery sealing systems, marine pump stations, and other industrial sealing zones that require oil-tolerant elastomers.
