13MM (.512) BUNA-N ORING CORD 70 DURO

Ordered as 0M284B13, this is a black Buna-N (Nitrile) 70 Shore A O-Ring Cord Stock built to a cross section of 0.512 in (13 mm). The o-ring cord stock supports field repair of oversized or non-standard sealing grooves without a special tooling charge.

The material holds up against water, greases and lubricants, and petroleum-based oils. Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. It is not the right choice where ozone and direct sunlight or polar solvents are present.

Maintenance and OEM teams specify it across fluid power, automotive, and agricultural equipment.

Stocked as 0M284B13 and sold by the foot. As always, verify media compatibility and operating conditions against the requirements of your specific application.
