5MM (.196) BUNA-N O RING CORD 70 DURO

The 0M284B5 is a black Buna-N (Nitrile) 70 Shore A O-Ring Cord Stock with a cross section of 0.196 in (5 mm). This o-ring cord stock eliminates long lead times on large-diameter custom rings.

The material holds up against water, hydraulic fluids, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is known for strong abrasion and tear resistance, low compression set under sustained load. Applications involving automotive brake fluid or polar solvents call for a different compound.

You will find this material specified across hydraulic and pneumatic systems, agricultural equipment, and automotive.

Order part number 0M284B5, sold by the foot. 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.
