The PBR 0.375x0.750x0.250 TC NBR Oil Seal is engineered for compact rotating equipment where effective lubricant retention and contamination exclusion are essential for operational reliability.

The TC Profile is one of the most widely used rotary shaft seal designs worldwide. It incorporates a primary sealing lip energized by a garter spring together with a secondary dust lip that prevents dust, dirt, moisture, and contaminants from entering the equipment. This dual-lip design significantly improves sealing performance compared with single-lip oil seals.

The rubber-covered outer diameter enhances sealing performance between the seal and housing while compensating for minor housing imperfections. The integrated spring maintains constant sealing pressure on the shaft throughout the service life of the seal.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the seal provides excellent resistance to lubricating oils, grease, hydraulic fluids, and petroleum-based lubricants. NBR remains the most commonly used sealing material because of its outstanding balance of oil resistance, flexibility, durability, and affordability.

With dimensions of 0.375 x 0.750 x 0.250 inch, this seal is commonly used in small electric motors, miniature pumps, gear reducers, automation systems, electric tools, conveyors, and imported inch-size equipment.
