Upgrading your Bosch AQT pressure washer hose can be tricky if you're not 100% sure on adaptors, but these hose fitting kits will help make it a bit easier. 

Domestic pressure washers usually come with accessories that feel like an afterthought such as the hose, often a cheap kinking plastic hose. Now you're likely looking at upgrading your high pressure hose to an Uberflex or AR High Pressure Hose. You'll need some straight forward adaptors to get it going, so we've got a Bosch hose fitting kit that's already been figured out for you so you can upgrade your setup quickly. 

There are only two different kits to choose from. Check the variants to help compare what you're working with. 

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.
