-109 BLACK BUNA 70D O-RING

APG stocks the H70MD109, an AS568-109 black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 0.299 in (7.59 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.505 in (12.83 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. This material stands up to petroleum-based oils, greases and lubricants, and hydraulic fluids. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

This item is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across general industrial maintenance, agricultural equipment, and automotive.

H70MD109 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
