Grease gun 101

[D2Cat]

Some folks have been using grease gun for years and keep fighting the connection between the gun tip and the zert. Here's a short video to overcoming that problem.

Lock and lube A total game changer

Good video , thanks for posting!
My question is this, while looking at the coupler in the video it is obvious that your able to loosen and tighten the jaws , not all couplers have this feature do they?

I have a few grease guns that have couplers that look like these replacement Milwaukee grease gun couplers, which I just replaced with a lock n lube. when I first received the Milwaukee I tried, with just hands to unscrew the tip and it was tight. I did not put it in my vise and with a wrench try to loosen. I assumed the knurling on the coupler is to aid in pulling it off a zirk.

I had same experience with my Milwaukee grease gun tip…whom ever tightened it, I’d like to ask that their supervisor cut the handles off all that associates wrenches. I am certain the lock N lube tip that I installed is not on near as tight, and no issue that I am aware of yet.

The knurled-portion is to provide gripping-surface to twist the barrel CW or CCW to loosen to to firm-up the grip on the zerk. Virtually All grease guns have this adjustment….largely unknown to most owners who then seek other tips such as Lock-N-Lube.

The standard knurled fitting is fine as long as you have easy access to the zerks. When you have fittings on implements that aren't readily accessible, the LockNLube is the only way to go!!! Even on accessible fittings, it makes the job much faster. I have both the standard and the XL...well worth the $$.

Agreed.

But there are those of use who are so lazy (like me, the laziest SOB south of the Mackinac bridge) that simply do not want to "twist and untwist" the coupler.

F'it,.......... for 14 dollars give me the F'ing "lock and lube"

I hate greasing sh^t and every second that I don't have to do it is money well spent.......(Just a cranky old former A&P mechanic spouting off)

Carry on......

I started greasing our farm equipment many decades ago. We filled guns from a barrel by sucking it into the gun barrel, or bare-handed if you’re a little kid and couldn’t get the grease to pull in. No cartridges.

Adjustable couplers were a given.

I’ve had a hell of a time with the couplers I’ve gotten last 30 years. Some I simply can’t loosen up…maybe cheap Chineseum…probably wrecked a couple trying. Figured they gave up on the feature.

I’ve got a couple kicking around here somewhere. I should try again…

lock and lube works good if it fits. On the stuff I deal with, most of the time it doesn't fit. I gave it to the new guy the other day and went back to old faithful.

surprised how many don't realize a quick 1/2 turn of the the coupler most times locks it onto the fitting and frees both hands to operate the gun to start the lubing. no need to spend money on replacement that does same thing.

The original lock and lube I suppose free and already available on almost all guns I have come across.

nice too post and educate for sure. good reminder. good find.

Man, that gives me "flashbacks" for sure.

Packing those grease guns by hand was a messy chore.

And Lord help you if you if you got an "air pocket" in that tube......I can't tell you how many times I was way out at the end of the flight line, in the rain, at 0200, trying to hold a flashlight, while doing a grease job (called a 14 day inspection) and the grease gun would crap out due to hitting an air pocket Hahahahahh....OMG

And come "hell or high water", those damn pilots and Maintenance Officers demanded that those birds be ready by flight time.

I think I am closer to solving why I swear so much.

I certainly don't miss it.

I think the operating theory is you adjust the nozzle tension so that a little force is required to insert the nozzle over the zerk. The pressure of the grease being forced into the zerk is supposed to displace the clamshells inside the nozzle, thus increasing their grip upon the zerk.

There is a sweet spot to the adjustment. Once found, you shouldn't need to disturb it.
