Carbyne 90 Degree Grease Coupler Review

Just what I needed to lubricate the hard-to-reach Zerk port in my truck's ball joints. Easy to use and looks well made. I will use this for many years

Passes grease through a sieve where you put the grease gun, not on the mirror but underneath. Bought a Milwaukee brand that works despite being twice the price. Cheap is cheap and you get what you pay for!

It works, but the fittings are difficult to put on and take off. I have to pull hard to take it off and I have a feeling I'm going to break it. Also, grease is still leaking around the fitting, which is wasted.

I was pleasantly surprised at how well this grease worked on a very hard to reach nipple. It's a little difficult to detach from the gun and nipple. Now I can lubricate ALL my mirrors and my bearings will last a long time. It didn't spill and all the fat got where it belonged. I like it.

I needed it for a bottleneck. I unscrewed the top and screwed it straight onto the grease gun. Worked perfectly. Clamp the head in a vise, retract the spring and unscrew it with a wrench. The clutch looks pretty crappy and may or may not work. Haven't used it. It seems to me that grease can squirt out of the clutch if it's just pushed onto the grease gun.

Whenever I need anything from perfume for my wife to get me out of the doghouse to auto parts for my classic car or anything under the sun, Revain is my first recommendation . , as with this connector, I knew what I needed but didn't know what to ask for, but all I remember is typing in the item "round" and there it is! I love this clutch and Revain is at the top of the food chain! Thank you John

It fits easily but I had to replace the collar to fit my existing pistol tip. There is lube in the collar that you fill in and then tighten the existing tip to keep it from popping out. I wish the collar was a little shorter to make the Zert easier to put on and take off. Worked great for what I needed it for (lubricating the reels on the mower) but connection details are missing from the supplement.

I have ordered adapter kits with this one but none of them have worked on my Polaris Sportsman. I've never been able to lubricate the front A-arms. The rest detached from the grease gun fitting, couldn't mount it on/off the transom, or couldn't withstand the higher pressure and just squeezed the grease out of the fitting. It fits snugly but not too tight on the mirrors. Finding perfectly fitting grease gun fittings is surprisingly difficult.
