Aquatouch Pressure Washer Adaptors | M21 (F) to M22 14mm (M)$14.95 About Aquatouch Pressure Washer Adaptors
Got a pressure washer or accessory with an oddball M21 male thread and need to step up to standard M22? This adaptor is your clean solution.
The Aquatouch M21 Female to M22 14mm Male Adaptor lets you convert popular Gerni & Stihl pressure washers to the more common M22 thread system, which means you can run an upgraded pressure washer hose. It’s a great way to get rid of that cheap, kinking plastic hose you're probably getting tired of.
Built from solid brass, this fitting is corrosion resistant and high pressure rated. No plastic threads, no leaks, just a proper connection where you need it.
Features
- Thread Conversion: Converts M21 male fittings to M22 14mm male threads, opening up compatibility with aftermarket hoses.
- Solid Brass Construction: Long lasting, corrosion resistant and capable of handling high pressure loads.
- Leak-Free Design: Precision machined threads offer clean sealing without excess tape or fiddling.
Compatibility & Upgrades
- Designed specifically for Gerni & Stihl series electric pressure washers, and other machines that utilise this M21 thread.
- Upgrading the hose on an internally plumbed Gerni or Stihl hose reel model is currently not possible with our fittings.
- This M21 adaptor is what you need if you have a male thread exiting the pressure washer where your stock hose would connect.
- The other side of the M21 adaptor is a male M22 14mm thread, which gives you access to other adaptors or an aftermarket hose like the ProPulse Uberflex or Annovi Reverberi 15m hose.
- Setting up a new hose? See the Pressure Washer Hose Fitting Kit for Gerni / Stihl / Nilfisk, or browse all pressure washer fittings & adaptors.

Great little adaptor—solid brass build and feels really durable. Used it on a friend’s Gerni pressure washer to connect an M22 hose and it worked perfectly. Fits snug, installs in seconds, and stays completely leak-free. Makes upgrading to better hoses and accessories super easy—definitely a must-have if you’re ditching OEM fittings.
