The ALEMITE AL42030 is a button head grease fitting coupler designed for use with standard grease guns in lubrication maintenance applications. This coupler connects to button head fittings, allowing grease to be injected into bearings, joints, and other lubrication points found in mechanical equipment. It is a single-piece fitting sold individually and weighs 0.25 pounds. Lubrication technicians, mechanics, and service professionals working on industrial or commercial equipment rely on this type of coupler for routine preventive maintenance tasks.
The AL42030 is suited for use wherever button head grease fittings are specified. Common applications include heavy equipment, fleet vehicles, agricultural machinery, and industrial assemblies that require periodic grease service. The coupler attaches to the end of a grease gun hose or rigid extension, forming a secure connection to the fitting point on the equipment being serviced.
Designed as an OEM-style replacement coupler for use with standard grease guns equipped with button head grease fittings in lubrication service applications.
Installation is performed by lubrication technicians or mechanics as part of routine equipment maintenance. Relieve pressure from the grease gun before attaching or removing the coupler. Ensure the button head fitting on the equipment is clean and free of debris before making the connection to prevent contamination of the lubrication point. Follow equipment manufacturer service intervals and applicable workplace safety procedures when servicing lubrication points.
