## Overview

The LockNLube Grease Gun Coupler is a stainless steel, leak-proof fitting tip designed for effortless, hands-free greasing. Compatible with all grease guns and Zerk fittings, it locks securely under pressures up to 10,000 PSI and features a quick-release thumb lever for easy removal even under pressure. Fully rebuildable with included replacement seals and jaws, it ensures long-lasting, mess-free lubrication for professional-grade maintenance.

## Description

The LockNLube Grease Coupler is compatible with all grease guns and grease fittings. It does not leak once locked on and will not pop off under pressure. No hands are needed to align or hold the coupler in place while greasing. You have both hands free to operate your grease gun and know that the grease will go in, not on, your machine. Guaranteed. It has a unique sliding sleeve, activated by a thumb lever. The sleeve locks the four spring-steel jaws onto the Zerk fitting, and releases the jaws by pushing on the thumb lever. When the jaws are locked onto the Zerk, a leak-proof seal is created. The locked connection is positive and rigid preventing the coupler from coming loose and breaking the leak-proof seal. If a fitting becomes pressurized, especially a recessed one, just depress the thumb lever and release the coupler. The LockNLube Grease Coupler is fully rebuildable. If it starts to leak, you simply replace the seal and jaws and it is as good as new. See our tutorial here. We include a free replacement seal and jaws with every coupler that we sell. Additional Seal Kits are also available from our store.

## Questions & Answers

**Q: Does this work with Milwaukee grease guns?**
A: This does not work on the older Milwaukee m18 grease guns. They used a metric threaded hose on the older ones. The newer guns have standard thread and it will fit those. Take the current connector off the end of your grease gun hose. If the first 1/8 inch of the hose is not threaded, then you have a metric hose and this lock lune will not fit.

**Q: Where is this product manufactured?**
A: It is a quality product made in South Africa by Gurtech.

**Q: After installing it, I couldn't depress the gun's pump. What did I do wrong?**
A: Between myself and friends we have successfully installed five of these fittings without any problems. As per the other reviews, I would first check your gun to see if was in fact pumping grease, then reinstall the coupler and try again, before you put it on a fitting. Could be that the fitting jerk that you tried it on was frozen. If it still does not allow grease to flow, it is defective and you will need to return it.

**Q: It is just the fitting or does it include the flexible line?**
A: It is just the fitting. The hose was included to give context and sense of scale.
