The REPCO 3.500x4.631x0.500 LGSP NBR Oil Seal is engineered for industrial applications where effective oil retention and protection against contamination are essential to equipment reliability and operational efficiency.

The LGSP Profile is specifically designed for rotary shaft sealing applications. Its robust construction helps maintain consistent sealing performance under continuous operation, vibration, and varying load conditions. The sealing lip is engineered to maintain proper contact with the shaft surface, minimizing lubricant leakage while protecting internal components from dust, dirt, moisture, and environmental contaminants. Radial shaft seals are commonly used to seal rotating equipment such as pumps, gearboxes, and power transmission systems.

Manufactured from high-quality NBR (Nitrile Butadiene Rubber), the sealing element offers 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, flexibility, wear resistance, and economical performance.

The durable construction makes this seal suitable for industrial gearboxes, pumps, compressors, conveyor drives, agricultural machinery, mining equipment, and imported industrial machinery operating in demanding conditions. It helps reduce lubricant loss, minimize downtime, and extend the service life of bearings and rotating components.

With dimensions of 3.500 x 4.631 x 0.500 inch, this seal is commonly found in heavy-duty industrial equipment and imported machinery utilizing inch-size shaft systems.
