LUMAXLX-1400-6 Silver 1/8" NPT Standard Grease Coupler (Pack of 6). Standard Grease Coupler. Fits All 1/8" NPT Threads. 4500 PSI (310 Bar) Maximum Operating Pressure.

Finally, a grease coupler that goes on solidly and stays on. Instead of trying to grease with one hand holding the fitting on and one hand and a leg and a foot and whatever trying to hold the grease gun and pump you can grease without getting grease all over the place most of the time.

This is the second-best grease gun tip I have used. The best are the ones that you can manually lock and unlock to the fitting, and are crazy good, but crazy expensive. For the price, I don't think these can be beat. They have the 4 little claws that grip the zerk, which seem a little more secure than the ones with only 3 claws. In fact, sometimes they seem to grip too good. Sometimes, if there is still pressure in the grease gun hose (from a partly plugged fitting or whatever) it can be hard to remove. If that happens to you, here's a litle tip. The front half of the tip is threaded into the back half, and if you loosen the front half about 3/4 turn, it will relax the grip on the fitting, making it very easy to remove. There seems to be some sort of seal between the halves, because I only keep the two halves tightened together finger-tight, and grease doesn't leak from the seam.Works better than most grease gun tips, for the price probably as good as any.

Good price on coupler.

I have several machines to grease in my business. The couplers on a few of my guns are getting worn, so I thought I'd try a six pack of the Lumax couples. The first one I tried pushed the grease around the outside of the fitting. Upon inspection I noticed one of the flanges inside the coupler end was missing. I tried a second one, it was really tight to get on the zerk. Once on, it took a lot of force to work the handle on the gun. Frustrated at this point, I placed my old coupler back on the gun and finished greasing. Will try the other four when I have more time. At this point, I can't say I'd recommend this product.

nice to have extra grease gun parts handy

The seal is soft and keeps blowing out with light pressure. sometimes I get 3-4 fittings, change it again.

It works but not for long I have to replace them often

I ordered these for my husband. He runs construction equipment which needs to be greased every day. At best they lasted 4 days

Ordered a 6 pack only recieved 4 (in a package for 6!) Followed the amazon steps to report to the seller to recieve the missing 2. NO RESPONSE. These are good couplers but when I pay for 6 I'd like to recieve 6.
