Real Time Saver, makes life so much easier.
Wish I had bought one years ago. No longer need both hands to grease equipment and vehicles. Yes it's a little pricey but well worth every penny. Very good quality and well built. Let me start by saying I hate grease guns, always have. The old hand pump ones that you put the tube in, really piss me off. Once you put it on the Zirk, it is such a PITA to get off. This handy little item makes greasing things so much easier. I would recommend this to anyone that finds greasing things unfun when you're trying to get the job done and you can't get the job done easily with the old-style grease guns.

Best purchase from Amazon 🌹✨
I required a nipple lock grease gun coupler for greesing machinary parts and inside bearings. It perfectly works in high pressure. Use thread lock sealer tape for perfect airtight between joints. It's works very well without any greese leakage and it comes with a 30cm cable hosing. Diameter fits perfectly for a 1/8 NPT Greese guns. Easier to attach and remove. Strong material. A bit heavier. I like it ❤️.

Very helpful product
Finally i could use my hand grease gun with ease. Greased three times and the clip grabs the grease nipple tightly and let the grease flow into the joints so effortlessly. I have two vehicles which require greasing of nipples. Thanks to this product i don’t have to go and wait for getting my vehicles greased. I am so happy not hear the excuses for not greasing joints properly. I would recommend this product. Without it i had a hard time pumping grease inside joints

Single person operation
Usually we need two people while greasing. One person holds the nozzle and the other pumps. But with this only one person is required. All well need to do is press the liver on the sides and place the nozel on the nipple, and then press the grease gun. But all greasing points needs to have the nipple without which this is of no use. Will definitely recommend. It's made of steel and good quality.
