PLG High Pressure Washer Quick-Disconnect Couplings,Male & Female Connectors

These quick connects are a perfect fit if you own a Sun Joe SPX or similar pressure washer, since these are 3/8" pressure washer quick connects with M22 thread and 15 mm inside diameter. Let's go over possible places where various quick connects can be installed. There are different quick connect types for different places.1. Pressure washer inlet (garden hose connects here)If you want your garden hose to quickly connect to your pressure washer, you need a quick connect designed for a garden hose. These are NOT the same as pressure washer quick connects. It does not matter if your garden hose is 1/2", or 5/8", or 3/4" in diameter, as long as it provides gallons-per-minute necessary for the pressure washer: all of these hoses will have a 3/4" Garden Hose thread (GH) at the ends. Consequently, all garden hose quick connects are designed for the same 3/4" GH thread, but vary depending on which end of the hose (male or female) they attach to.2. Pressure washer outlet (pressure washer hose connects here)This is one place where 3/8" pressure washer quick connect can possibly be installed.3. Pressure washer gun (the other end of the pressure washer hose connects here)This is another place where 3/8" pressure washer quick connect can possibly be installed4. Pressure washer extension wand (you may or may not have it; if you do, it connects onto the gun)This is the third place where 3/8" pressure washer quick connect can possibly be installed5. Nozzle (connects onto the gun or extension wand)This is where 1/4" quick connect is installed. Your pressure washer already has this. If you want to install other gizmos here (foam cannon, etc.) you may need more 1/4" quick connects. This is NOT the same as this product.So there are two or three places where you normally want to install 3/8" pressure washer quick connects. Unless, of course, you want to complicate things further and insert more gizmos between the pressure washer and pressure washer hose. But I am assuming a simple setup, where you have two connections at the ends of the pressure washer hose, and, perhaps, one more between the gun and the wand.It is the first two connections that I recommend to start with, as I found that this last connection (between the gun and the wand) makes the wand wobble. Unless you change the extension wand often (to attach a different wand or a different tool), you may find you do not need it to be quick connecting.Now, if you look at the ends of your pressure washer hose, you will see that they are equipped with a thread and an inner core with an o-ring. Consequently, when buying quick connects for these connections, you need to know two things: which thread it will be used with and the diameter of the inner core.From what I can tell, most pressure washers use M22 thread. But the inner core diameter differs between the manufactures. Most use 14 mm, while others (Sun Joe, etc.) use 15 mm. Find out what you need before ordering these.

A great upgrade to any pressure washer that doesn't have quick connect fittings.Very simple to install. I have these on all of my pressure washers. Definitely recommended.

Anyone with a pressure washer will tell you that quick connects are the way to go and I agree! Makes assembly and disassembly a breeze. I bought these for my SunJoe pressure washer and they work perfectly. The price is much better than many others on Amazon. I added Teflon tape to help ensure no leaks. I prefer these types of quick connects over the swivel head because they seem solid, more durable and professional. More of an opinion and personal preference honestly. I highly recommend.

I've looked all over the Internet for a 3/8" male nipple to M22 threaded female and could not find one. Even though I don't have a use for the couplers, I bought the set because I could not find the nipples anywhere else - which I find strange because it seems like a logical part. They also came with two extra rubber washers in case you need to remove and reinstall the fitting. As long as you don't over stress these, they should be fine.

Exactly what I needed for the Sun Joe SPX-3501 pressure washer. So far, so good.
