Saves the day!
Worked great for reaching a fitting on my center mower deck spindle. Had a fitting on the center spindle of my mower deck that faced a metal bracket and didn't have enough clearance for my current grease gun hose. This solved my problem.

Fits into tight places and locks
LockNlube has done it again - produced a great product. I have 3 of their excellent locking heads and love them for most uses. The only drawback is that the diameter of the tips is wider than normal zerk greasing tips, not allowing it to fit into some tight spaces and forcing you to resort to a conventional greasing tip. This new right angle greasing tip is just as narrow as a conventional one It can slip on a zerk fitting easily, lock - grease - unlock and slide off with little effort. All it takes is a small barrel rotation to lock and unlock. It attaches to your grease gun via a zerk fitting on the end eliminating the need to permanently screw anything on your gun. This also provides some extra flexibility. What a fantastic invention! Now, I wish LockNLube would come out with a straight version of this little gem.

Simple tool gets you into tight spaces.
Helped me grease one of the bearings on my pellet stove augur that I couldn’t reach any other way. Definitely easier than disassembling the stove. If it leaks, you haven’t tightened it on enough.

Great fit for counter sunk zerks.
This is exactly what I needed. I bought 3 other angled zerks and though they were nice they just would not work. an area where I needed to get to was recessed and this is the only one that was of the standard width so it would fit within the area. The others I tried were too large and simply would not fit.

It works, but thats about it.
Does the job, but good god is it a fight to get it on and off a zerk.

Works perfectly!
This adapter works perfectly when I need to grease a few hard to reach fittings on my backhoe. I use it in combination with a lock-n-lube nozzle on my grease gun which helps keep the adapter connected correctly with no mess.

i am using it on my Outlander ATV where the grease points are difficult to access. it helps if you use it with the LockNLube Grease Gun Coupler.

Useless, total waste of money, leaks around zerk/grease nipple when applying grease. Poor quality.
