-413 WHITE BUNA 70D FDA O-RING

H70FDA413 is an AS568-413 white Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 2.975 in (75.57 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.525 in (89.54 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to water, many alcohols, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving strong acids or polar solvents call for a different compound.

This o-ring meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include agricultural equipment, automotive, and fluid power.
