LockNLube Pistol-Grip Grease Guns – Heavy Duty & Premium Models (LNL153-450 & LNL252-450)

High-quality one-hand operated pistol-grip grease guns designed for reliable, leak-free greasing. The Heavy Duty model (LNL153) features a rugged steel/cast head and outputs up to 5,000 PSI, while the Premium model (LNL252) has a lighter cast aluminum head and can deliver up to 8,000 PSI for the toughest fittings. Both guns include the LockNLube® Grease Coupler, a 20″ high-pressure hose with in-line swivel, an air bleeder valve, and a Loop & Lock™ handle clip for clean storage.
