Carbyne 90 Degree Grease Coupler/Adapter. Access and Lubricate Fittings in Tight Spaces. from a Family-Run Tool Company Based in The U.S.A.

It connects simply but I had to swap out the collar to fit over my existing gun tip. There is a grease zert in the collar that you plug into then tighten down your existing tip so this doesn't pop off. Wish the collar was a little shorter to make tightening onto and loosening off of the zert easier. Worked great for what I needed it for (greasing spindles on riding mower) but detail on just how it connects is lacking in the add.

I needed this for a tight spot. I unscrewed the top and screwed it directly on the grease gun. Worked perfect. Put the head in a vice, pulled back the spring back and used a wrench to unscrew it. Coupler looks kinda cheezy and may or may not work. Didn't use it. Looks like to me grease may squirt out of the coupler as it just fits over the grease gun.

I purchased this adapter to grease the steering grease fittings on my 2005 GMC Sierra K1500 pickup. They are a nightmare to grease because there is inadequate clearance above to get a straight grease fitting in place. I just pushed the end of the grease gun onto the nipple in the adapter and it has stuck on there with no problem. I wish I had bought this thing sooner.

Needed to grease a hard-to-reach fitting behind the engine of my boat that was really close to the hull. This 90-degree elbow is solid and very easy to press on to the fitting, it also attaches directly to the existing nozzle of my grease gun.

It works, but it's hard to get it seated on and off of the fittings. I have to yank on it pretty hard to get it off and I feel like I'm going to break it. It also still leaks some grease around the fitting that gets wasted.

If you have to have a tool that pisses you off, this is the tool for you. Why, you ask? Here are the reasons:1. Leaked at the coupling to my grease gun hose.2. Tried different grease gun. Still leaked.3. Tried tightening the grease zerk in the coupler, still leaks.4. Prayed to Satan to get this thing to stop leaking.5. Still leaks.

I've ordered sets of adapters that included one like this, but none have worked on my Polaris Sportsman. I've never, been able to grease the front A arms until now. The others popped off the grease gun fitting, couldn't get it on/off the zerk or couldn't take the higher pressure and just oozed grease out of the fitting. It fit tight, but not too tight on the zerks. It's surprisingly hard to find grease gun fittings that have the 'just right' fit.

I sort of knew grease was going to come out from all over from some other reviews but I was going to take it apart anyway and just use the 90 degree fitting but yeah I attached it to a grease gun as is and as soon there is a little bit of resistance the grease came out from all over the place, where it connects to the grease gun and the elbow. I took it apart and just used the 90 degree with a grease gun I already had, that 90 degree part still leaked grease from the fitting to the the elbow but I added some teflon tape and seems to hold now.So it works for me in parts, i used the neck for another grease gun that it was too long and all I didn't use was the spring and the quick connect part.I guess you could put teflon tape all over but the quick connect part I don't think you can make it work right no matter what.
