About this item

The LockNLube coupler clamps onto Zerk fittings and locks in place, so you can grease machinery with both hands free and no mess. It has a 1/8" NPT threaded connection that fits manual, battery, and pneumatic grease guns, and it handles both SAE and metric fittings. A patented thumb lever lets you release it instantly even under pressure, and it's rated up to 10,000 PSI. Measuring 3.45" L x 1.66" H x 0.63" W, it's built from steel and rubber and comes with a rebuild kit (spare nitrile seal and four hardened steel jaws) for long-term use.

• Clicks and locks right onto Zerk fittings, so the grease goes into the machine, not all over your hands.
• Thumb lever releases it in a second, even under pressure, great for tight or recessed fittings.
• 1/8" NPT threads work with manual, battery, and pneumatic grease guns.
• Fits both SAE and metric Zerk fittings.
• Rated up to 10,000 PSI, made from steel and rubber to handle heavy daily use.
