See how easy it is to replace the seal and steel jaws on your LockNLube® Grease Coupler
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.

Saves a lot of money on grease not leaking
Love it good product and good customer service thank you !!!
After finally getting the factory grease coupler off my Lincoln grease gun, it must have been glued on. Anyway the LockNLube coupler appears to well made and the other parts I ordered seem that way as well. I haven't used any of them yet but will in the spring. I haven't used them so only 4 stars.
Works great! No leaks and preforms as advertised.
A++ once you try it you will never want to use a regular grease tip again
