The REPCO 1.875x2.500x0.438 TCN NBR Oil Seal is engineered for rotating equipment requiring dependable sealing performance and long service life. It is widely used in industrial pumps, gearboxes, electric motors, reducers, hydraulic systems, agricultural machinery, and OEM rotating equipment where reliable lubricant retention and contamination protection are essential.

The TCN Profile is a high-performance rotary shaft oil seal consisting of a rubber-covered metal case, a spring-loaded primary sealing lip, and an auxiliary dust lip. The rubber-covered outer diameter improves static sealing between the housing and the seal while compensating for minor housing imperfections.

The spring-loaded primary lip maintains consistent sealing pressure against the rotating shaft, minimizing lubricant leakage throughout the operating life of the seal. The auxiliary dust lip prevents dirt, dust, water, and abrasive particles from entering the sealing area, helping extend the service life of bearings, shafts, and internal components.

Manufactured from premium NBR (Nitrile Butadiene Rubber), this seal provides excellent resistance to:

• Mineral oils
• Hydraulic oils
• Gear oils
• Lubricating grease
• Petroleum-based lubricants

NBR offers excellent abrasion resistance, flexibility, and durability for general industrial applications. Typical operating capability is up to 0.5 Bar, with operating temperatures ranging from -40°C to +100°C, depending on operating conditions.

With dimensions of 1.875 × 2.500 × 0.438 inch, this oil seal is commonly installed in industrial gearboxes, pumps, electric motors, compressors, agricultural machinery, conveyor systems, hydraulic equipment, and OEM rotating machinery utilizing inch-size shaft systems.
