Free delivery on eligible orders. Review: I think it’s brilliant - Bought one because the allu bucket that’s fitted to the machine wasn’t taking grease. Well it is now !! Simple to use and fit to the grease gun hose. Just click and pump. Less mess and less struggling with the grease nipples and clean hands when I have just greased the whole machine. I’m delighted with it. Was a bit concerned about the size and fitting it onto recessed nipples but so far it’s been perfectly fine on the little 14 ton excavator and fitted on them all. Would recommend. Review: Works well, but..... - Works well, but one joint was gummed up with hardened grease. The gun just wouldn't pump. Testament to the seal that this product forms at the nipple that no matter how hard I squeezed the gun, there was no leak at the nipple. Hence 5 stars. I'll need to use one of those unblockers to clear the joint out. ## Features - 【Locking and sealing】Our Saker grease gun coupler Reinforced jaws and quality sealing gasket ensure long lasting and stable performance,prevent leakage even at 14,000 PSI extreme pressure. - 【Robust Build Quality】This high quality grease gun coupler built with premium quality zinc coated alloy steelfor for all-day performance in the shop or garage,heavier and stronger than any other grease couplers on the market. - 【One Hand Operation】Grease gun coupler with smooth retraction mechanism allows one-hand operation.No need to hold while greasing,after locking the grease gun coupler,you can free your hands to operate the grease gun. - 【Unique Design 】Upgraded grease gun coupler have the unique and patented Retract Mechanism pull back the inner seal and leave outer socket ring wide open,which help locating zerk fittings at blind spot. - 【Wide Application】The Saker portable grease gun coupler fits all 1/8 NPT standard grease guns,mini grease guns,It also fits all DIN and SAE grease fittings,simply replace your existing grease gun couplers.This heavy-duty tool is an excellent device to have on a construction job site or in an auto mechanic garage to use on your large machinery.It is also a great lubrication tool to have at the farm for your tractor, plow, stump puller,disc harrow,seeder,etc. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09VSTLVCW | | Best Sellers Rank | 1,407 in Automotive ( See Top 100 in Automotive ) 37 in Garage & Workshop Equipment | | Brand | Saker | | Customer Reviews | 4.0 4.0 out of 5 stars (3,358) | | Date First Available | 18 Mar. 2022 | | Item Weight | 110 g | | Manufacturer | GJ25777 | | Manufacturer part number | GJ25777 | | Manufacturer reference | GJ25777 | | Package Dimensions | 16 x 11 x 3.9 cm; 110 g | ## Images ![Grease Gun Coupler-Upgrade to14000 PSI,Duty Quick Release Grease Couplers,Compatible with All Grease Guns 1/8" NPT Fittings(1 PC) - Image 1](https://m.media-amazon.com/images/I/61XnqFsQwlL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Where is this Grease Gun Coupler made?** A: Quickest way to tell if an items made in China or Mexico is no COO listed. Dead giveaway imo. I just assume the worst when a seller/maker fails to list the COO. Because for decades corps have not only known their customers want higher quality USA, Japan or German made products but they also know we don't want China-Mexico crappyola. Meaning? By listing a better COO its the best/cheapest advertisement there is today. They get asked where their products made every day so they'd proudly display a good COO & hide the bad ones where possible. Amazon should force each listing to fill in COO but thats helping buyers which they no longer do. **Q: What exactly does this do that others dont?** A: What it does it lock on to the zerk/grease fitting. You don't need to hold it on. No more mess anywhere. It's really worth the money. When you work on cars & those grease fitting are in weird areas (tie rod end between tire & strut) you can use 1 hand & not make a mess. 1 hand on grease gun to hold it & the other hand to pump it in. Great concept. **Q: Will valve release from a pressure locked zerk?** A: It is a mechanical lock to the grease zerk. Mechanically it can released with the lever. Regular grease couplers are spring loaded and release by pulling and release by over coming pressure of the grease, if any. So far they have released, sometimes with a little extra thumb pressure. Good question. **Q: Does this 2nd gen version have a smaller barrel diameter (5/8") to fit tighter recessed fittings? Or is it still 3/4" dia.?** A: The main barrel is larger than 5/8", probably closer to 11/16", but less than 3/4". Where it attaches (screws) to the hose is larger than 3/4". ## Customer Reviews ### ⭐⭐⭐⭐⭐ I think it’s brilliant *by A***R on 25 July 2024* Bought one because the allu bucket that’s fitted to the machine wasn’t taking grease.
