The REPCO 1.750x2.846x0.4375 M/R NBR Oil Seal is engineered to provide reliable sealing performance for rotating shafts operating under industrial conditions.

The M/R Profile utilizes a reinforced metal outer case combined with a precision-engineered NBR sealing lip. This proven construction provides excellent dimensional stability while maintaining consistent contact pressure on the shaft surface, helping prevent lubricant leakage and contamination ingress.

The sealing lip effectively retains lubricating oil and grease within the equipment while protecting bearings, shafts, and internal components from dust, dirt, moisture, and abrasive particles. The reinforced metal case ensures secure housing retention even in applications exposed to vibration and continuous-duty operation.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the seal offers excellent resistance to mineral oils, hydraulic fluids, gear oils, grease, and petroleum-based lubricants. NBR remains the industry-standard sealing material due to its excellent oil resistance, abrasion resistance, flexibility, and cost-effective performance.

With dimensions of 1.750 x 2.846 x 0.438 inch, this seal is commonly used in industrial pumps, gearboxes, electric motors, agricultural machinery, conveyors, compressors, and OEM equipment utilizing inch-size shaft systems.
