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.

United StatesLOVE my Lock N Lube!!
We have 10 DeWalt grease guns at work. I put a Lock N Lube tip on mine when they first came out and now EVERYONE has one on theirs lol!!!

The concept is nice and when new it works good. But after greasing a mini excavator 8 times it leaked big time and I had to rebuild the tip. At a cost of apx $10 plus shipping per rebuild kit you’ll be spending a lot of money constantly rebuilding the tip. I was told it would last months but it actually lasted day. Perhaps if you grease only occasionally then it might last months but if you own equipment that need to be greased daily you will be buying lots of rebuild kits
