Need a reliable seal for your project? These Othmro Nitrile Rubber O-Rings are built to handle tough conditions. Each ring has an outer diameter of 220mm (about 8.58 inches), an inner diameter of 202.8mm (7.91 inches), and a thickness (wire diameter) of 8.6mm (0.34 inches). You get two in a pack, both made from black nitrile rubber (NBR), which is known for its excellent resistance to oils, fuels, greases, and many chemicals. It's also pretty durable against wear and heat, making it great for automotive, plumbing, hydraulic, and industrial applications. The round cross-section provides a solid seal between overlapping surfaces, commonly used in engines, valves, pumps, and flanges. Just keep in mind that nitrile isn't the best for ozone, strong acids, or UV exposure, so avoid those environments. Installation is straightforward—just make sure the surfaces are clean and free of debris. Always double-check your measurements before ordering to ensure a proper fit. These O-rings offer good flexibility and a long service life. A handy addition to any mechanic's or DIYer's toolkit for sealing tasks!
