Description
The LockNLube Grease Coupler is a patented, heavy duty grease gun coupler engineered to lock securely onto standard Zerk fittings using a thumb-activated sliding sleeve, creating a true hands free, leak free connection that will not pop off under pressure. Its hardened steel jaws grip the fitting firmly while an internal seal directs grease straight into the bearing instead of leaking around the coupler, improving efficiency, reducing mess, and ensuring proper lubrication. Built for professional and industrial use, the coupler is fully rebuildable, compatible with most standard grease guns, and designed to deliver long service life even in demanding shop, agricultural, and field maintenance environments.
