LockNLube Mini Grease Gun Kit — Compact 3 oz. Tube Grease Gun with Patented Locking Coupler, 12" Hose & In-line Swivel

The LockNLube Mini Grease Gun Kit is a compact, toolbox-ready lubrication tool that locks onto fittings, prevents leaks, and delivers grease through a 12" hose with an in-line swivel for tight access.

Designed for mechanics, fleet technicians, hobbyists and anyone who needs fast, reliable lubrication in confined places, this mini kit combines a patented LockNLube grease coupler with a heavy-duty 12-inch hose and an in-line swivel. The kit accepts standard 3 oz. grease tubes and is sized to slide into toolboxes or vehicle storage compartments, so you can carry professional-grade functionality in a small package.

How does the LockNLube coupler stay attached without leaking?

The patented LockNLube coupler uses a secure locking mechanism that clamps to standard grease fittings and holds pressure while you pump, minimizing mess and preventing accidental detachment. Because it forms a tight seal, grease is directed to the bearing or fitting rather than dripping from the coupler.

• Patented locking design prevents accidental release during use
• Sealing geometry reduces backflow and surface leaks
• Works with standard zerk-style fittings for wide compatibility

What makes the 12" heavy-duty hose and in-line swivel useful?

The 12-inch hose gives extra reach into recessed or awkward positions that rigid guns can’t reach, while the in-line swivel rotates freely to reduce hose twist and improve control. Together they let you maintain proper nozzle orientation without straining or repositioning the tool.

• 12" reinforced hose for durability and extended reach
• In-line swivel prevents kinking and eases directional changes
• Improves access to recessed or angled grease nipples

What grease cartridges does this kit use and how portable is it?

The mini gun accepts common 3 oz. grease tubes, so refills are inexpensive and widely available. Its compact footprint is optimized to fit into most toolboxes, service vans, and on-board storage compartments—making it a convenient choice for mobile technicians.

• Compatible with standard 3 oz. grease cartridges
• Small form factor stores easily in toolboxes and compartments
• Lightweight for carrying between job sites or vehicle duties

How does this kit help reduce service time and cleanup?

By locking securely to fittings and directing grease efficiently, the kit reduces retries and wasted product. The swivel and flexible hose speed access to multiple greasing points, while the leak-resistant coupling cuts down on cleanup after service.

• Fewer lost fittings and less re-situating saves time per service point
• Reduced drips mean less cloth and solvent cleanup
• Ergonomic handling speeds repetitive lubrication tasks

Who is this for? The LockNLube Mini Grease Gun Kit is ideal for professional mechanics, fleet maintenance crews, agricultural operators, and DIYers who need a compact, reliable lubrication solution. If you want a portable tool that reaches tight grease fittings, minimizes mess, and works with standard 3 oz. cartridges, this kit provides a practical, durable option for routine maintenance and on-the-go repairs.
