Should the need arise to demount the connection unlock the nut and push the collet towards the body of the fitting and pull the pipe to release. The fitting ensures an easier working environment in confined places, is approved for behind the wall installations, and removes the need for hot works on site. Installation can be reduced by around 40-Percent when compared to traditional fixing methods.

Review: Anyone With a Milwaukee 4 Gallon Sprayer Needs This - The Milwaukee 4-Gallon sprayer is a wonderful invention but a small design flaw with the final connector that seperates the fluid suction to the plastic tank is this plastic peice. Somehow milwuakee did not fully pass the R&D testing and this peice does indeed fail and leaks. The simple fix is a 1/4" tube that could have plugged into this and onto the recieving pump adapter and all leaks go away. The threads are simply not rated to spec on the milwuakee plastic molding. Your best to just dremmel it off and use this peice. $5 and your backpack sprayer will be leak free. Easy to install. Be sure to grab some 1/4" tubing as well. You only need half an inch but you will need to buy a spool of it for a few bucks.
Review: John Guest fittings take the pain out of plumbing - John Guest fittings work with PEX, CPVC, and copper tubing . The important word in that sentence is WORK , I'm a big fan of PEX because it is flexible, CPVC and copper are not, but properly installed JG fittings do a foolproof, leakproof ,job that anyone with a tape measure , proper cutting tool, and a DYS attitude can be proud of ,using any of the three materials. JG fittings have other big plus going for them, they are removable, and reusable , never corrode, are very cost effective, and come in a wide range of fittings, in every size. SO no plumber, no wrenches, no soldering, no taping, etc etc VS snip , push,click and done. PS desertcart sells PEX tubing, PEX cutters, CTS [copper tubing] cutters, sent to your door , every thing you need , Personally I'd rather have a root canal than spend hours in a BIG BOX store trying to find what I need , getting only 1/2 my list and all the aggravation !!!
