The PBR 1.438x2.375x0.375 TC NBR Oil Seal is a precision-engineered rotary shaft seal designed to prevent lubricant leakage while protecting machinery from dust, dirt, moisture, and external contaminants.

The TC Type is one of the most widely used oil seal profiles in industrial applications. It features a spring-loaded primary sealing lip that maintains consistent contact pressure against the shaft, while the secondary dust lip provides additional protection against contaminants.

Manufactured from NBR (Nitrile Butadiene Rubber), this oil seal provides excellent compatibility with mineral oils, grease, hydraulic fluids, and general industrial lubricants. The material offers an excellent balance of durability, flexibility, and cost-effectiveness for general industrial applications.

The 1.438 x 2.375 x 0.375 inch size is commonly found in imported machinery, pumps, reducers, motors, agricultural equipment, and industrial rotating systems requiring reliable sealing performance.
