Standard / Nonasbestos Gasket Material

ASTM F-104: F332949M8

NV-519 is a cellulose fiber material with thermoset resin and nitrile butadiene rubber binder. It has excellent tensile strength, crush resistance, and erosion resistance against high volume fluid flow and impingement. It is used primarily in automatic transmission valve body, pump, and accumulator/ channel plate applications as well as carburetors and air compressors. It is intended for use in applications with short duration maximum temperatures up to 180°C (350°F).
