The UNIVERSAL 1.688x2.502x0.750 G2 NBR Oil Seal is engineered for industrial rotating equipment requiring dependable lubricant retention and enhanced protection against external contaminants. The seal is suitable for applications where continuous operation, equipment reliability, and extended service life are critical.

The G2 Profile is a heavy-duty industrial rotary shaft seal design featuring a reinforced metal outer case, a spring-loaded primary sealing lip, and an additional auxiliary dust lip. This dual-lip configuration provides superior protection compared with single-lip seals by retaining lubricants while simultaneously preventing dust, dirt, moisture, and abrasive particles from entering the equipment.

The primary sealing lip is energized by a garter spring that maintains consistent radial pressure against the shaft surface throughout the service life of the seal. This helps ensure effective sealing performance even under varying operating conditions and minor shaft wear.

The auxiliary dust lip acts as a secondary barrier against contamination, helping protect bearings, gears, and internal rotating components from premature wear. This feature is especially valuable in industrial environments where airborne contaminants, dirt, and moisture are present.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the seal provides excellent resistance to mineral oils, hydraulic fluids, gear oils, lubricating greases, and petroleum-based lubricants. NBR offers outstanding oil resistance, flexibility, abrasion resistance, and cost-effective sealing performance for general industrial service.

The reinforced metal case ensures dimensional stability and secure housing retention, making the seal suitable for gearboxes, pumps, reducers, compressors, agricultural machinery, and heavy-duty OEM equipment operating under demanding conditions.

With dimensions of 1.688 x 2.502 x 0.750 inch, this seal is commonly used in industrial pumps, gearboxes, speed reducers, agricultural equipment, conveyor systems, compressors, and OEM rotating machinery utilizing inch-size shaft systems.
