1.000" ID X 1.437" OD X .250" OIL SEAL

Fluoroelastomer/FKM/Viton oil seal, item OSV-1000-1437-0250-TB-H, for rotary shaft sealing, oil retention, grease retention, and bearing protection in industrial equipment. This rotary shaft seal is described as metal OD, double lip, with spring based on the available attributes, giving customers a clear view of the lip design, spring detail, and outside-diameter construction when those details are available. The actual dimensions are 1 inch (25.4 mm) ID x 1.437 inch (36.5 mm) OD x 0.25 inch (6.35 mm) cross-section/height, making the part easier to compare against shaft size, housing bore, and seal width requirements. Oil seals are commonly used on gearboxes, motors, pumps, rollers, gear reducers, and rotating assemblies where lubricant must stay inside the housing while dirt, moisture, and debris are kept out. FKM/Viton material is used where elevated chemical and heat resistance are important compared with standard nitrile materials. The wording naturally supports product searches for oil seal, rotary shaft seal, nitrile oil seal, FKM oil seal, rubber covered OD seal, single lip oil seal, and double lip oil seal as applicable. Item OSV-1000-1437-0250-TB-H is included for SKU-level identification in equipment records, drawings, maintenance lists, and reseller product catalogs.
