M22 14mm to M22 Metric Fitting

I have an AR Blue 390ss that uses the somewhat strange 22x15 threads versus the more standard 22x14. I recently purchased a pistol grip for use with it which came with the adapter to accept the pressure hose from the AR unit but that required unscrewing the wand and screwing on the pistol grip so I wanted quick connects. These were inexpensive, well made, didn't leak a single drop and I realize that the 3/8 male quick connect side is actually a universal fit and so I can use my devices with my other pressure washer which is a Karcher. I can also quick change during a project (after depressurizing the hose first!) between the wand and the pistol grip. I do have a couple of suggestions to those that are getting leaks with these. Do not use teflon tape, there is no need for these type fittings, they make use of an o-ring to seal. Secondly, and more important, lubricate the fitting before screwing these on. Use a water soluble lubricant (astro glide works great but your buddies will wonder why it's in your tool box but let them use their imaginations) to coat the inside of the brass fitting. This prevents the o-ring from tearing, the number one reason these things leak. It will also make disassembly at some point in the future much, much easier. The water soluble lubricant won't damage anything inside the pump itself but you don't need a lot of it - half the size of a pencil eraser is plenty. It also lets you push the male side far enough into the female side for the threads to bite - very important because it will resist due to the tight fit (this is starting to sound like a cheesy romance novel!). Oh, and if you buy this set by mistake and insert your 22x14 hose into it, it will go together just fine, the external threads will match up just fine but it will leak like a sieve because the o-ring isn't making contact properly. Lots of people have done this, unaware that there is this strange difference in sizes that to the naked eye, look exactly the same.

After returning my 15mm quick connect that didn't fit my electric pressure washer and got the 14mm it fit perfectly no leaks! Not sure about the brand my electric pressure washer is but it works perfectly didn't need no teflon tape also

Great functionality, quality and value for the money. Ease of installation is simple and provides a quick connection for my foam cannon with no leaks. Would definitely buy again!

Product works as intended. Well built. Had a problem with leaking and finally figured it out after several on again/off again installs - the 15mm plug (the side with the black grip) is threaded into the rest of the part with a metric hex wrench (Allen wrench). There is an o-ring at the base of the threaded part that you can't see that helps create a tight seal/fit. On this one (I bought two) the o-ring was wedged between the two pieces and sliced. Put on a new o-ring (size is very important), screwed pieces back together and voila - fixed no leaks.

First off let me start off by saying if you have any power washer that is anything other than commercial that does not have quick connects chances are you need a 14 mm version of this. I purchased the 15 mm on accident because I'm not familiar with the metric system whatsoever and I don't know why they put it in millimeter in America but aside from that 14 mm is the number because 15 is too big and will not seal on the inside where the gasket goes around. It's extremely easy to install I simply unhooked my existing pressure washer hose from the wand itself because I wanted to be able to utilize the hose that was there and if need be add on with the commercial hose that I have that will now click in and the heads you can use are unlimited. It made it very easy now I can use my extension pole power wash head that had a quick connect as it is a commercial model by simply unhooking whichever I'm using currently and hook that one up and it is ready to go instead of being limited to the same power washer wand or head technically. You'll thank me later for less than $10 I'm extremely happy and it only takes literally 2 minutes to do if even that. You will need a crescent wrench or open-end wrench of that size and probably a pair of channel locks to remove the existing wand from the factory hose that did not have the quick connect unless you're planning on doing it at the pump itself which you can do it that way just the same.

The gun on my DeWalt 3800# pressure washer broke. OEM Repacements on ebay were discounted from over $90 to $54, but I noticed the description said they were built by Simpson. I remembered seeing Simpson guns here and bought one here for under $30. To fit my hose I had to get an M22 to14 adapter. The pair of adapters here are several dollars less than just the female 22 mm here cost at the big box store. Perfect fit and I was able to save the 30" wand from my DeWalt.

ease of removal

Had a SunJoe pressure washer and wanted to quickly be able to swap spray guns for different applications. This fit perfectly on both the pressure washer hose and the gun itself; no leaks or issues thus far. Perfect!

Prodotto di qualità

The internal 15mm Swivel does not fit into a Ryobi pressure washer hose connection....although it should. Also, unlike other quick connect kits, it doesn't snap together in a "quick connect" fashion - you have to pull it down, push in the nozzle in, and then force the ring back up to make the connection work. Disappointing.

Pièce de qualité Inoxydable 👍

Great quality item. The machining is on point with quality threading. No leaks and solid acting on the quick release.
