2.4mm (CS) x 5.3mm (ID) Buna-N (NBR) 70A Duro Metric O-Ring

An O-ring, or torus, is a doughnut-shaped object or mechanical gasket generally made from an elastomer. O-rings can also be made from PTFE, other plastic materials, metals, and be made hollow or solid. O-rings often have a round cross-section. O-rings commonly provide a pressure and fluid seal between cylindrically shaped, overlapping mating surfaces and are commonly used for engines, faucets, flanges, valves, and various cylinders. NITRILE/BUNA-N (NBR) Nitrile, more commonly known as Buna-N, o-rings are the most popular and widely used o-rings because of their low cost, good mechanical performance and resistance to water, most basic oils, lubricants and some fuels. Buna-N o-rings typically tend to function well in applications that have limited temperature and resistance requirements.
