.275 BUNA-N 4 LOBE CORD 70 DUROMETER

Ordered as 0Q284275, this is a black Buna-N (Nitrile) 70 Shore A quad profile O-Ring Cord Stock measuring a cross section of 0.275 in (6.99 mm). The o-ring cord stock supports field repair of oversized or non-standard sealing grooves without a special tooling charge.

It resists water, greases and lubricants, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is known for reliable performance in both static and dynamic service, low compression set under sustained load. It should not be specified for service in polar solvents or strong acids.

Common environments for this compound include general industrial maintenance, hydraulic and pneumatic systems, and agricultural equipment.

This item is sold by the foot under part number 0Q284275. 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.
