Keep your machinery running smoothly with this professional-grade EAI oil seal! The 40mm x 55mm x 8mm TC double lip design with garter spring provides superior sealing performance that prevents lubricant leaks while keeping dirt and contaminants out of your equipment. Made from high-quality nitrile rubber with a carbon steel spring, this seal is built to handle temperatures from -40°F to 226°F and resists hydrocarbon fluids like grease, mineral oil, hydraulic fluids, and petroleum oil. The metal case reinforcement gives it extra rigidity for a tight, secure fit, while the rubber coating ensures stable sealing ability. The double lip design is key - one lip keeps lubricants in, the other keeps contaminants out, and the garter spring maintains constant pressure on the shaft for effective sealing over time. This seal is perfect for automotive applications, motorcycles, shock absorbers, engines, gearboxes, bearings, axles, and all sorts of industrial machinery. The 70A hardness rating means it's durable enough for long-term use without wearing out quickly. Installation is straightforward and won't damage your equipment when done properly. Before ordering, just double-check that the 40x55x8mm size matches what you need. EAI manufactures these to OEM specifications, so you're getting quality that matches original equipment parts. Protect your investment and prevent costly breakdowns with this reliable oil seal that's engineered to perform in tough conditions!
