Navigating the maze of connections when attaching your PF22 Foam Cannon to your pressure washer can be a daunting task, often leaving users bewildered by a tangle of hoses and fittings. Fear not! This guide is here to simplify the process for you. We’ll provide clear instructions to ensure seamless integration of your foam cannon with your pressure washer. Say goodbye to confusion and hello to hassle-free cleaning!

M22 threads are common on pumps, hoses and spray guns. Below is a photo showing the measurements of these fittings. The outer diameter of the M22 is 14mm and the inner plug on the female side is 14mm. The female side has the o-ring to prevent leaking. Now, a different fitting can measure 15mm, so we have two different adapter kits to help you here.

The 14mm Adapter Kit includes 2x stainless garden hose plugs (for pressure washer inlet and garden hose spray gun), 1x stainless garden hose coupler (for garden hose outlet), 2x stainless 3/8 QC coupler X 14mm M22 plug (for hose ends), 2x stainless 3/8 QC Plug X 14mm M22, and 1x coupler (for pump outlet and OEM gun Inlet). Generally these adapters work with Ryobi, Simpson, Karcher and Kranzle pressure washers.

If you find yourself needing 15mm fittings, the 15mm Adapter Kit is a great choice. This kit includes 2x stainless garden hose plugs (for pressure washer inlet and garden hose spray gun), 1x stainless garden hose coupler (for garden hose outlet), 2x stainless 3/8 QC coupler X 15mm M22 plug (for hose ends), and 2x stainless 3/8 QC Plug X 15mm M22 Coupler (for pump outlet and OEM gun inlet). Generally these adapters work with Sunjoe, Ryobi, and Greenworks pressure washers.

Both kits are in stainless steel, for great overall durability.

After narrowing down the adapter size needed, the below charts will show the fittings and where they will fit within your washer setup.
