LockNLube® Grease Coupler Care & Maintenance:

Keeping your grease coupler free of grit and dirt will extend the life of the seal. If you get grit in the end, give it a quick spray with some WD-40® and/or compressed air. Consider using a Coupler Cap and Zerk Fitting Caps to keep your equipment clean.

STEP-BY-STEP INSTRUCTIONS FOR CHANGING THE SEAL ON YOUR LOCKNLUBE® GREASE COUPLER

STEP 1 – SQUEEZE THE LEVER TO DETERMINE WHERE TO ATTACHED THE VISE OR VISE-GRIP PLIERS

When squeezing the lever, see the portion of the flat steel exposed at the base of the coupler. This is where you will attach your vise or vise-grip pliers.

STEP 2 – ATTACH THE VISE OR VISE-GRIP PLIERS TO THE LOCKNLUBE® GREASE COUPLER

The vise, or pliers, will only have a small piece of the coupler to attach to, so don’t be afraid to crank down on them and get a tight grip. When depressing the lever, you can see that the steel jaws of the seal kit are exposed and ready to be replaced.

STEP 3A – REMOVE OLD SEAL KIT

Using a pair of vise-grip pliers, get a very firm grip on the steel jaws of the seal kit. Because the jaws will be greasy and may rotate, you’ll need to really squeeze them. Don’t worry about damaging the jaws or the interior cone with your wrench, as these will all be replaced in a moment. Once you have loosened the interior cone by rotating the pliers counterclockwise, you can remove the pliers and continue to twist with your fingers.

STEP 3B – REMOVE OLD SEAL KIT

After loosening the inner cone you can remove the seal kit by hand by continuing to pinch and twist the steel jaws until they can be removed.

STEP 4 – ASSEMBLE THE NEW SEAL KIT

The steel jaws have one edge larger than the other, this is the edge that should go at the top (large end) of the cone. Placing a small amount of grease on the inner cone first can help to ensure that the jaws stick and don’t fall out before being placed in the LockNLube® Grease Coupler.

STEP 5 – INSERT THE NEW SEAL KIT

Holding the four steel jaws in place, put the new seal kit into the LockNLube® Grease Coupler. Once inserted, then can be twisted by hand until the jaws start to slip on the inner cone.

STEP 6 – TIGHTEN THE NEW SEAL KIT USING VISE-GRIP PLIERS

You should loosen your pliers before gripping the new seal kit. Unlike the removal process, you should be able to tighten the new seal kit without applying too much pressure. Once the inner cone feels snug, you are ready to use your LockNLube® Grease Coupler again.

Very pleased

Purchased LockN Lube a few years, have been extremely happy with the attachment on my Milwaukee grease gun. Utilized replacement kit that was included with L-n-L. Ordered two repair kits recently online for backup. Very good invention
