The REPCO 3.500x4.375x0.375 LGSP NBR Oil Seal is engineered for industrial applications where effective lubricant retention and contamination exclusion are critical to maintaining equipment reliability and operational efficiency.

The LGSP Profile is designed for rotary shaft sealing applications and provides stable sealing performance under continuous operation, vibration, and varying load conditions. The sealing lip maintains proper contact pressure with the shaft surface to minimize lubricant leakage while preventing dust, dirt, moisture, and environmental contaminants from entering the equipment. Rotary shaft seals are commonly used in industrial pumps, gearboxes, conveyors, and power transmission systems.

Manufactured from high-quality NBR (Nitrile Butadiene Rubber), the sealing element provides excellent resistance to lubricating oils, hydraulic fluids, gear oils, grease, and petroleum-based lubricants. NBR is one of the most widely used sealing materials because it offers an excellent balance of oil resistance, flexibility, wear resistance, and economical performance.

The robust construction makes this seal suitable for industrial gearboxes, pumps, agricultural machinery, mining equipment, conveyor drives, compressors, and imported industrial equipment operating under demanding conditions. The seal helps reduce lubricant loss, extend bearing life, lower maintenance costs, and improve equipment reliability.

With dimensions of 3.500 x 4.375 x 0.375 inch, this oil seal is commonly found in heavy-duty industrial machinery and imported equipment utilizing inch-size shaft systems.
