MTM Hydro SRG Adaptor Kit

Many consumer-grade electric pressure washers from brands like Sunjoe, Ryobi, and Greenworks use a proprietary 15mm M22 fitting rather than the industry-standard 14mm size. If your current hose or wand connection feels loose or leaks when using standard 14mm accessories, you likely have the 15mm version and need this specific kit to bridge the gap.

Yes, once installed, this kit converts your proprietary 15mm connection to a universal 3/8-inch quick-connect system. This allows you to easily swap between foam cannons, different spray nozzles, and extension wands without needing to thread them on manually.

While it is primarily designed for electric models that feature the 15mm M22 stem, it can be used on any pressure washer that utilizes this specific 15mm proprietary fitting. Always verify the measurement of your machine's outlet before purchasing to ensure a proper fit.

The kit is constructed from high-quality brass for the primary fittings, which provides excellent resistance to corrosion and wear. It also includes stainless steel components to ensure a secure, leak-free connection during high-pressure operation.

No special tools are required for installation. You can typically tighten the fittings by hand, though using a pair of pliers or a wrench to ensure they are snug is recommended to prevent any pressure loss or leaks.
