-005 BLACK BUNA 70D O-RING

Ordered as H70MD005, this is an AS568-005 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 0.101 in (2.57 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.241 in (6.12 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

Buna-N (Nitrile) is specified here for reliable performance in both static and dynamic service, strong abrasion and tear resistance. This material stands up to petroleum-based oils, many alcohols, and hydraulic fluids. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or ozone and direct sunlight will shorten service life.

This o-ring is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across automotive, hydraulic and pneumatic systems, and construction equipment.

Reference part number H70MD005 when ordering; the item is sold individually. Nominal inside diameter is listed as 3/32 inch. Review your operating media and conditions against this specification before installation.
