The REPCO 5.500x6.375x0.500 LGSP NBR Oil Seal is engineered for industrial rotating equipment where reliable lubricant retention and protection against contaminants are critical for operational efficiency and equipment longevity.

The LGSP Profile is specifically designed for rotary shaft sealing applications. Its robust construction helps maintain consistent sealing performance under continuous operation, vibration, shock loads, and varying operating conditions. The sealing lip is engineered to maintain proper contact pressure against the shaft surface, minimizing lubricant leakage while preventing dust, dirt, moisture, and environmental contaminants from entering the equipment.

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 in industrial applications because of its excellent balance of oil resistance, wear resistance, flexibility, and economical performance.

The heavy-duty construction makes this seal ideal for industrial gearboxes, pumps, mining machinery, crushers, conveyor systems, agricultural equipment, compressors, and power transmission systems operating under severe service conditions.

With dimensions of 5.500 x 6.375 x 0.500 inch, this oil seal is commonly used in imported industrial machinery and heavy-duty rotating equipment requiring reliable long-term sealing performance.
