This 10piece TC oil seal set provides a reliable sealing solution for smalldiameter shaft applications with an inside diameter of 12 mm. The kit includes rubber frame oil seals in fluorine rubber and butadiene rubber, as well as threaded oil seals. All seals are sized 12 x 28 x 8 mm and are offered in the color option listed as NBR. Key benefits Precise fit for 12 mm innerdiameter shafts, reducing oil leakage and protecting internal components. Material options for broad chemical and oil compatibility: fluorine rubber (FKM) frame seals and butadiene rubber (NBR) seals, plus threaded oil seal designs. Threaded oil seal design provides secure mounting and resistance to loosening in dynamic applications. Ten pieces in one set offer quick replacement and spare parts for ongoing maintenance or multiple assemblies. Compact dimensions (12 x 28 x 8 mm) suitable for smalldiameter equipment without requiring large housings.
