The UNIVERSAL 1.688x2.625x0.375 TG NBR Oil Seal is engineered to provide reliable sealing performance for rotating shafts operating under industrial conditions where lubricant retention and contamination exclusion are critical.

The TG Profile incorporates a spring-loaded primary sealing lip combined with an auxiliary dust lip. This dual-lip configuration effectively retains lubricants while preventing dust, dirt, moisture, and abrasive contaminants from entering the equipment. Compared with single-lip oil seals, TG seals provide enhanced protection and improved service life.

The primary sealing lip utilizes a precision garter spring to maintain consistent radial pressure against the shaft surface. This ensures stable sealing performance and minimizes lubricant leakage during continuous operation. The additional dust lip acts as a secondary barrier, helping protect bearings, gears, and other critical rotating components from external contamination.

The reinforced metal case construction provides dimensional stability and secure housing retention under vibration, varying temperatures, and continuous-duty operation. This makes the seal suitable for industrial equipment requiring dependable long-term performance.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the sealing element provides excellent resistance to lubricating oils, hydraulic fluids, gear oils, grease, and petroleum-based lubricants. NBR remains one of the most widely used sealing materials due to its excellent oil resistance, wear resistance, flexibility, and cost-effective performance.

With dimensions of 1.688 x 2.625 x 0.375 inch, this seal is commonly used in industrial pumps, gearboxes, electric motors, compressors, agricultural machinery, conveyor systems, and OEM equipment utilizing inch-size shaft systems.
