.375 BUNA-N 4 LOBE CORD 70 DUROMETER

The 0Q284375 is a black Buna-N (Nitrile) 70 Shore A Quad-Ring Cord Stock supplied with a cross section of 0.375 in (9.53 mm). This quad-ring cord stock lets you fabricate a quad-ring seal to any circumference without a special tooling charge.

The material holds up against propane and butane, many alcohols, and water. Buna-N (Nitrile) is valued for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. It should not be specified for service in ketones or automotive brake fluid. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and lower compressive load required to achieve a seal.

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