I'm not advocating or promoting the following products--I'm just reporting on some locking grease gun tips I ran across this week.
The theory is that these special tips lock on grease zerks and eliminate the need to hold the tip of the grease gun against the zerk while you pump grease. It's a small thing, but it can be annoying and awkward to try and hold a grease gun tip in place when zerks are in odd or hard-to-reach places.
The first locking grease gun tip is called a "Lock-n-Lube," and uses a small finger-actuated paddle on the side of the tip to engage/disengage the tip from a zerk. The other locking tip doesn't have a trade name, but is manufactured by Univer-Co in Canada. It looks like a miniature hydraulic coupler, about the same size as a standard grease gun tip. It automatically locks on a zerk when you press it in place, then you slide back a small collar when you want to remove it.
I bought one of the Univer-Co locking tips, and so far I like it. Only time will tell if it's durable and will consistently connect without leaking grease. If it works, great. If it doesn't, I'll just add it to the other tools and gadgets in my junk drawer that I was suckered into buying.
If you're interested in either of these locking grease gun tips, you can Google "Lock-n-Lube" to find where and how to buy them. The Univer-Co tips are popping up at equipment dealerships and hardware stores around the country, or you can find them on Amazon by looking for "Univer-Co grease gun tip" on the Amazon site.
What can I say--my wife has a closet full of shoes she doesn't wear, and I have a tool drawer full of tools and gadgets that I thought I had to have...
