The PBR Oil Seal 1.4375x2.375x0.375 GP NBR is engineered for industrial rotating equipment where effective lubricant retention and contamination exclusion are critical to operational reliability.

The GP profile incorporates a primary sealing lip energized by a garter spring together with an auxiliary dust lip. This double lip design helps retain oil and grease inside the equipment while preventing dust, dirt, moisture, and external contaminants from entering the sealing zone.

The rubber-covered outer diameter improves sealing between the housing and seal body while reducing installation leakage risks. The garter spring continuously maintains radial contact pressure on the shaft surface, ensuring consistent sealing performance throughout the service life of the seal.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the sealing element provides excellent resistance to lubricating oils, hydraulic fluids, grease, and petroleum-based lubricants. NBR remains the industry's most commonly used oil seal material due to its excellent balance of durability, flexibility, oil resistance, and cost efficiency.

With dimensions of 1.4375 x 2.375 x 0.375 inch, this seal is commonly used in industrial gearboxes, pumps, electric motors, agricultural machinery, conveyors, and imported inch-size equipment.
