The REPCO 1.500x2.187x0.4375 TCN NBR Oil Seal is engineered for demanding industrial applications where superior sealing performance and contamination protection are essential.

The TCN profile is one of the most popular heavy-duty oil seal designs used worldwide. Unlike conventional single-lip seals, the TCN design incorporates a primary sealing lip with garter spring, a secondary oil control lip, and an additional dust exclusion lip. This triple-lip construction provides enhanced protection against dust, dirt, mud, water splash, and other contaminants while maintaining excellent lubricant retention.

The reinforced metal case construction ensures dimensional stability and secure housing retention under vibration and heavy operating loads. This makes the seal particularly suitable for agricultural equipment, hydraulic systems, gearboxes, construction machinery, and industrial rotating equipment.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the sealing element offers excellent resistance to lubricating oils, hydraulic fluids, gear oils, grease, and petroleum-based lubricants. NBR remains the preferred material for industrial oil seals due to its excellent wear resistance, flexibility, oil resistance, and cost efficiency.

With dimensions of 1.500 x 2.187 x 0.4375 inch, this seal is commonly installed in hydraulic pumps, agricultural machinery, industrial gearboxes, conveyor systems, construction equipment, and imported inch-size machinery.
