The REPCO 2.750x4.133x0.781 G2 NBR Oil Seal is engineered for industrial rotating equipment requiring reliable sealing performance in applications where conventional single-lip oil seals may not provide sufficient protection.

The G2 Profile is a specialized rotary shaft oil seal design featuring a rubber-covered metal case, dual sealing lips, and two independent garter springs. This construction allows the seal to effectively separate lubricants or fluids while maintaining excellent sealing performance in compact housing arrangements. The dual-spring design helps maintain consistent radial pressure on both sealing lips, improving sealing efficiency and extending service life.

Unlike standard oil seals, the G2 design provides additional sealing capability between two media or fluid zones while maintaining excellent lubricant retention. This makes the profile particularly suitable for gearboxes, reducers, pumps, and industrial machinery where reliable sealing performance is critical.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the seal offers excellent resistance to mineral oils, gear oils, hydraulic fluids, lubricating greases, and petroleum-based lubricants. NBR provides outstanding wear resistance, flexibility, and long-term reliability in industrial operating environments.

The rubber-covered outer diameter improves housing sealing performance by compensating for minor housing imperfections while reducing leakage around the outside diameter.

With dimensions of 2.750 x 4.133 x 0.781 inch, this seal is commonly used in industrial pumps, gearboxes, reducers, compressors, power transmission equipment, and OEM rotating machinery utilizing inch-size shaft systems.
