The REPCO 2.125x3.500x0.750 G2 NBR Oil Seal is engineered for industrial rotating equipment requiring reliable sealing performance, lubricant retention, and protection against external contaminants.

The G2 Profile is a robust industrial oil seal design utilizing a reinforced metal case and a precision-engineered sealing lip energized by a garter spring. The spring maintains consistent radial pressure against the shaft surface, ensuring effective sealing performance while minimizing lubricant leakage during continuous operation.

This heavy-duty design helps protect critical machine components from dust, dirt, moisture, and other contaminants that can cause premature wear of bearings, gears, shafts, and rotating assemblies. The reinforced construction also provides excellent dimensional stability and secure housing retention under vibration and varying operating conditions.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the sealing element provides excellent resistance to lubricating oils, hydraulic fluids, gear oils, grease, and petroleum-based lubricants. NBR remains one of the most widely used sealing materials due to its excellent balance of oil resistance, wear resistance, flexibility, and cost-effectiveness.

With dimensions of 2.125 x 3.500 x 0.750 inch, this seal is commonly used in industrial gearboxes, pumps, compressors, agricultural equipment, hydraulic machinery, conveyors, and OEM rotating equipment utilizing inch-size shaft systems.
