M22 15mm High Pressure Sprayer and Wand Upgrade Kit for Pressure Washers - Perfect for Car Washing, Home Cleaning, and Outdoor Surface Maintenance

Description

For many years, I used the OEM pressure washer sprayer and wand that came with this unit. To this day, I’m guessing that many people still use these parts because of cost and/or the lack of awareness that something better exists. This setup can work (and did work for me) but I wanted something that did more than just worked, I wanted the absolute best sprayer and wand setup for my .

When you hear me talk about “wanting the best”, I’m talking about the quality of the product and the ease of use. In my experience using any OEM pressure washer parts, I have always found that the hose was janky, the sprayer was crap, or the wand was ridiculously long. I don’t want you to ever think that this is acceptable. If you’re looking to get the best use out of your pressure washer while also having the best user experience, you’re going to want to upgrade these parts.

To make it easy, I’ve broken the sprayer and wand kit I sell down into these three tiers - Basic, Advanced, and Ultimate. Check out the “What You Get” tab to see what comes in each kit. 

Let’s jump into the upgraded sprayers and why they are super legit. When looking for aftermarket sprayers, I came across the . It was a great sprayer that I enjoyed but it had limitations to it. I can tell you that I had many moments of frustration while washing my cars where the hose would get tangled and I would yank the darn thing in anger. 

So, because of this, I reached out to MTM and had them make the SGS-28; a well-built, swiveling sprayer that was based on the SG-28, but has all stainless steel internals. The reason why you want a swiveling sprayer is because it alleviates the issue of the pressure washer hose getting tangled and twisted. If you’re just starting out and are looking to get in the game, this is a great option. 

Now, if you’re looking to step it up a notch, you’ll want to look at the . Like the MTM SGS-28, the Original Mosmatic Sprayer has a swivel. The difference is that the swivel on the advanced sprayer is made by Mosmatic and is of much higher quality - it swivels much smoother. The trigger mechanism is also a lot more stout, yet requires very little effort to engage. I install PRIMA fittings on the Original Mosmatic Sprayer to help keep costs down. MTM = Chinese-made / more affordable. PRIMA = US-made / Mid-Range. Mosmatic = Swiss-made / extremely high quality. 

Now, let’s get into the big leagues: the . This is my pride and joy. Lots of money and time went into developing this sprayer. This piece uses all the best connections and hardware available in the market. It also swivels but the swivel and QD (quick disconnect) is built into the handle reducing the bulk on the inlet of the sprayer, making it much more ergonomic. Once you get this thing in your hand, you’ll wonder why you didn’t get it sooner. 

Along with having an upgraded sprayer, you’ll also be getting a really solid wand to accompany it. I have two options: the  that comes in the basic and advanced kits and the  that comes in the ultimate kit. These wands both have a 20° bend in them to make rinsing the roof or the lower portions of your car easier. The notable differences between these two are the fittings and the rubber nozzle protector. The Original Mosmatic Wand uses MTM fittings and has a nozzle protector installed on the wand already. The OG Spec Wand uses Mosmatic fittings and has no nozzle protector. This is because the nozzles that come in the Ultimate Kit have the protector. 

Nozzles are also an important part of your pressure washer accessories and need to be upgraded. The nozzles that come with the pressure washer are prioritizing pressure over flow. For washing cars, flow is king. The nozzles I provide are some of the best out there. In the basic and advanced kits, you get a  from MTM. In the ultimate kit, you get the . 

My advice to you is to invest the money to get what’s best and what works extremely well.
