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.
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.
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.
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.
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.
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.
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.

This is the best grease coupler I’ve ever used. We were replacing 2 or 3 a month and still experiencing a lot of frustration until we found out about these!!
Works great on my Milwaukee grease gun even on stubborn fittings that are clogged up and don’t want to take grease. Only bad thing is how fast they have to be rebuilt, I have to rebuild it every 6 months or so but well worth it to make greasing equipment easier
Been running a case of grease a week through the Lock & Lube for a year and a half now greasing Caterpillar equipment & it still works like new. Never fails to securely grab a zerk.
Works great I’ve had others that didn’t stand up this is my second rebuild kit and I ordered two so I wouldn’t be with out when this one wore out
Maintaining a fleet of equipment isn’t an easy task, the lock n lube has made it much easier to get the grease where and needs to go.
