The LINCOLN INDUSTRIAL LNI-4417 is a Value Series 40:1 single-acting grease pump assembly designed for use with a 120 lb. drum. This pump provides professional-quality lubrication at an affordable price, making it ideal for small garages, farmers, oil distributors, and auto dealers. Lincoln lubrication fittings are used in the automobile, agricultural, marine, truck, construction equipment and machine manufacturing industries. The true spherical contour of the fitting head provides a natural ball and socket joint between the fitting head and any commercial hydraulic coupler for a wide-angularity of contact, and a tight metal-to-metal seal.
