STHIRA® Grease Gun Coupler, Strong Lock Release Grease Coupler with 12" Spring Flex Hose, 12000 PSI Quick Release Metal Grease Gun Couplers Compatible with All Grease Guns 1/8" NPT Grease Gun Fitting : desertcart.in: Home Improvement

Review: 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.

*by R***D on 8 April 2024*

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 ❤️.
