The PBR 1.125x1.875x0.375 TGP NBR Oil Seal is engineered to provide reliable sealing performance for rotating shafts operating in industrial and mobile equipment.

The TGP Profile utilizes a spring-loaded primary sealing lip combined with an auxiliary dust lip. This dual-lip design helps retain lubricants inside the equipment while preventing dust, dirt, moisture, and abrasive contaminants from entering the sealing area. Double-lip oil seals generally provide longer service life and improved equipment protection compared with single-lip designs.

The primary sealing lip maintains consistent radial pressure against the shaft through an integrated garter spring. This ensures stable sealing performance while minimizing lubricant leakage during continuous operation. The additional dust lip serves as a secondary barrier against external contamination, helping protect bearings, gears, and other critical rotating components.

The reinforced metal case construction provides excellent dimensional stability and secure housing retention, even under vibration and varying operating temperatures. This design makes the seal suitable for industrial applications where reliability and durability are critical.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the sealing element offers excellent resistance to mineral oils, hydraulic fluids, gear oils, grease, and petroleum-based lubricants. NBR is widely recognized for its balance of oil resistance, wear resistance, flexibility, and cost-effective performance.

With dimensions of 1.125 x 1.875 x 0.375 inch, this seal is commonly used in industrial pumps, gearboxes, electric motors, agricultural machinery, compressors, and OEM equipment utilizing inch-size shaft systems.
