Got a leaky shaft? This EAI oil seal is here to fix that. The specs are 17mm inner diameter, 30mm outer diameter, and 7mm thick. It's made from FPM/FKM material (often called Viton), which is super resistant to heat, oils, fuels, and chemicals. The seal has a double-lip design: one lip keeps the lubricant (oil, grease) in, and the other keeps dust and dirt out. The stainless steel spring inside puts constant pressure on the shaft to ensure a tight seal. It can handle temperatures from -26°C to 230°C (-15°F to 446°F), so it's tough enough for most automotive and industrial applications – think engine components, axles, pumps, bearings, and gearboxes. When you're replacing a seal, matching the size and material is key, and this one is built to OEM specifications for a reliable fit. A proper seal prevents leaks that can damage your machinery and cause bigger problems down the road. If your 17x30x7 seal is worn out, this is a high-quality replacement that will get the job done.
