The GARLOCK Model 71 Oil Seal 2.875x3.875x0.3125 NBR is part of the renowned KLOZURE® oil seal family developed for general industrial sealing applications. Model 71 features a bonded single-lip design without a garter spring, making it particularly suitable for grease retention and protection against dust, dirt, and external contaminants.

Unlike spring-loaded oil seals designed primarily for oil retention, Model 71 is optimized for equipment operating with grease lubrication and moderate shaft speeds. The simplified design offers reliable sealing performance while reducing friction and wear.

Manufactured from NBR (Nitrile Butadiene Rubber), the sealing lip provides excellent resistance to mineral oils, grease, hydraulic fluids, and common industrial lubricants. NBR remains one of the most widely used sealing materials due to its balance of durability, flexibility, and cost-effectiveness.

The 2.875 x 3.875 x 0.3125 inch size is commonly used in industrial gearboxes, electric motors, conveyor systems, agricultural machinery, pumps, fans, and general rotating equipment requiring dependable grease retention and contamination protection.
