D-7201
Hydro-Fused® / Nonasbestos Gasket Material
ASTM F-104: F729900B4E33M9
Material Description:
D-7201 is a high density, fully cured nitrile butadiene bound gasket material that offers excellent mechanical strength, sealability, and erosion resistance to high pressure, high volume fluid flow and impingement. It is used in heavy duty automatic transmission valve bodies and other heavy duty applications, and is intended for applications with short duration maximum temperatures up to 290°C (550°F) and minimum continuous operating temperatures to -40°C/F.
