Pressure Washer Hose Fitting Kit | Gerni / Stihl / Nilfisk

This Gerni Adaptor Kit takes the guesswork out of upgrading your pressure washer hose with the exact fittings you need.

If you’re wanting to get rid of the cheap plastic hose your machine uses, maybe you’re tired of being stuck with an M21 threaded hose no one else uses or you just want to upgrade your high pressure hose to an Uberflex. You’ll need some straightforward adaptors to get it going, so we’ve got a Gerni / Stihl / Nilfisk fitting kit that’s already been researched for you so you can upgrade your setup quickly.

There are four different fitting kits to choose from. Check below to help compare what you’re working with at home. Gerni, Stihl and Nilfisk commonly use M21 threads on some models and then their own quick connect fitting on other models.

If you’ve already got an existing upgraded short gun like the MTM SG35 and are now looking at upgrading your hose, you’ll want the 3/8″ Adaptor kit below to connect you up to your gun.
