-208 BLACK BUNA 70D O-RING

H70MD208 is an AS568-208 black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 0.609 in (15.47 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.887 in (22.53 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs and low compression set under sustained load. It resists petroleum-based oils, greases and lubricants, and water. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or automotive brake fluid will shorten service life.

This o-ring is metal detectable for HACCP and foreign-body control programs. Typical settings include general industrial maintenance, construction equipment, and automotive.

H70MD208 ships individually. Nominal inside diameter is listed as 5/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
