JM Clipper 10485 H5L16 Single-Lip Spring-Loaded Rotary Oil Seal

The JM Clipper 10485 H5L16 is a new, solid single-lip spring-loaded rotary shaft oil seal from the well-established Clipper Oil Seals line, manufactured in the USA. Decoding the part number: "10485" is the JM Clipper seal number encoding the bore, OD, and width dimensions — this seal measures 1.048 in (approximately 26.6 mm) shaft bore × 1.5 in OD × 5/16 in width, consistent with JM Clipper's published catalog for this series; "H5" denotes the seal type/design series (heavy-duty elastomeric body with metal OD case), and "L16" indicates the lip material code — L16 corresponds to nitrile rubber (Buna-N/NBR), suitable for petroleum oils, water-based fluids, and common industrial lubricants up to approximately 250°F (121°C). The seal features a single primary sealing lip with a circumferential garter spring to maintain constant radial lip load against the shaft, an all-rubber outer diameter for positive housing retention without a metal case lip, and is visible in the photos with the stamped part number "10485 12" (date code) on the non-spring face. Typical applications include industrial gearboxes, pump shafts, conveyor bearings, and agricultural or light-construction equipment wherever a standard NBR single-lip seal is specified for petroleum-based lubricant retention.
