Need a reliable seal to stop leaks and keep dirt out of your machinery? This EAI double lip oil seal is built tough. It's made from FPM/FKM (that's like Viton) rubber combined with a fluoropolymer elastomer, so it can handle high temps from -26°C all the way up to 230°C. The inner stainless steel spring keeps constant pressure on the shaft for a tight seal, while the metal case adds rigidity. Dimensions are 55mm inside diameter, 90mm outside diameter, and 10mm thick – perfect for a precise fit. It resists oils, fuels, acids, and even ozone, making it great for cars, engines, bearings, axles, motorcycles, and industrial equipment. Stop worrying about lubricant leaks or contaminants ruining your gear. This seal is durable, corrosion-resistant, and designed to last. Easy to install and a smart upgrade to keep your machines running smooth.
