Product Specification

-
Part number H70MD413 is an AS568-413 black Buna-N (Nitrile) 70 Shore A O-Ring measuring 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). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs and low compression set under sustained load. It resists petroleum-based oils, water, and greases and lubricants. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C).

This o-ring is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include general industrial maintenance, agricultural equipment, and hydraulic and pneumatic systems.

H70MD413 ships individually. Review your operating media and conditions against this specification before installation.
