Mosmatic T304 SS M22 Female (15mm) to 3/8″ QD Plug Obsessed Garage

Until recently, none of these Mosmatic fittings existed. I worked closely with Jaimie from Mosmatic-US to have these made for us, the discerning prosumer. Keep in mind these weren’t built to a price point with sacrificed precision. I wanted these T304 stainless fittings at any cost, and my guess is that many of you do too. I get that this is more expensive than brass or Chinese-made stainless, but the fit, finish, and precision makes it worth it. What makes these new fittings so special is that they’re manufactured in Switzerland with much greater precision than typical fittings.

All of my new Mosmatic fittings come with a 6-month warranty, but I suspect they’ll last for quite a while. These couplers just have a satisfying action to them and even the sound they make sounds stout. 

Do keep in mind that these are consumable.  These are like tires that will be susceptible to wear and tear and future replacement.  They are just much better than normal.

This fitting is used to convert the outlet of a pressure washer from an M22 (15mm) connection to a ⅜” QD Plug. Use this T304 Stainless Steel fitting on Active, Comet, SunJoe, and AR Blue Clean Consumer pressure washers that have M22 (15mm) Male outlets so that a hose with QD couplers on it can attach to the pump. This Swiss-made fitting is the highest quality fitting on the market.
