Product Specification

-
H70MD175 is an AS568-175 black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 8.987 in (228.27 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 9.193 in (233.5 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to hydraulic fluids, water, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for low compression set under sustained load and the most widely specified general-purpose sealing elastomer. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ketones or automotive brake fluid.

This item is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include hydraulic and pneumatic systems, agricultural equipment, and construction equipment.

Stocked as H70MD175 and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
