.210 BUNA-N 4 LOBE CORD 70 DUROMETER

0Q284210 is a black Buna-N (Nitrile) 70 Shore A Quad-Ring Cord Stock measuring a cross section of 0.21 in (5.33 mm). In service, this quad-ring cord stock supplies profiled extrusion for grooves a round cord cannot fill.

Buna-N (Nitrile) is known for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. This material stands up to greases and lubricants, many alcohols, and hydraulic fluids. Verify compatibility before use with polar solvents or strong acids. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and lower compressive load required to achieve a seal.

Typical settings include automotive, fluid power, and hydraulic and pneumatic systems.
