*.070 BUNA-N 4 LOBE CORD 70 DUROMETER

APG stocks the 0Q284070, a black Buna-N (Nitrile) 70 Shore A Quad-Ring Cord Stock built to a cross section of 0.07 in (1.78 mm). A quad-ring cord stock supplies profiled extrusion for grooves a round cord cannot fill.

As a material, Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. This material stands up to propane and butane, petroleum-based oils, and many alcohols. Applications involving automotive brake fluid or ozone and direct sunlight call for a different compound. The profile itself contributes two sealing bands per contact face rather than one and lower compressive load required to achieve a seal.

Maintenance and OEM teams specify it across automotive, construction equipment, and general industrial maintenance.

Stocked as 0Q284070 and sold by the foot. Application requirements vary, so validate compatibility with your process conditions prior to installation.
