The REPCO 4.688x5.750x0.5625 TCN Silicone Oil Seal is engineered for industrial rotating equipment operating under elevated temperatures and challenging environmental conditions.

The TCN Profile incorporates a reinforced metal case, spring-loaded primary sealing lip, secondary sealing lip, and an additional dust exclusion lip. This triple-lip configuration provides superior oil retention while preventing dust, moisture, dirt, and airborne contaminants from entering the system.

Unlike standard NBR oil seals, Silicone elastomer offers significantly improved temperature resistance and maintains flexibility across a wider temperature range. This makes Silicone seals particularly suitable for equipment exposed to continuous heat, thermal cycling, outdoor environments, and applications requiring enhanced resistance to aging and ozone exposure.

The garter spring maintains constant radial sealing force against the shaft surface, ensuring reliable sealing performance even during prolonged operation and varying operating conditions.

With dimensions of 4.688 x 5.750 x 0.5625 inch, this seal is commonly used in industrial gearboxes, pumps, electric motors, fans, blowers, conveyors, agricultural equipment, and OEM machinery requiring high-temperature sealing capability.
