Review: Solid High Quality and Super Convenient - The McMillan quick connect works exactly as advertised. It’s well made, feels solid, and makes connecting and disconnecting fast and effortless. I’ve been using it regularly and haven’t had any leaks or issues at all. Installation was simple and it saves a lot of time compared to standard connections. Overall, great quality and very convenient — I’d definitely buy it again.
Review: Solid quality, good value for the money. - The perfect solution for washers with M22x14. I have been using stainless hardware for a good number of years now as I find they hold up better than brass and don’t corrode. This kit is actually a good value for all the parts included. They work great and perform exactly as I expected. These get fairly heavy usage and have been working great so far. I’m glad this kit was made available as it makes it easy to get all the parts you need.

## Features

- ⚠️ READ: Please verify you have an M22-14mm hose prior to purchasing. The male adapters have a plug with a diameter of 14mm, not 15mm. Therefore, it is not compatible with electric pressure washers from: Sun Joe, AR Blue, Simoniz and more. If your washer requires a 15mm fitting, using this fitting will cause leaks. Compatible with all gas powered pressure washers with M22 connectors.
- ✅ The Complete Solution: Every connector and adapter you need to convert all your connects on your pressure washer to full stainless quick connects, in one kit.
- ✅ Smooth Operation: The corrosion resistant stainless steel helps ensure smooth operation of the connects.
- ✅ Machined in Stainless Steel: Every connector is made out of 304 medical grade stainless steel, which does not rust or tarnish.
- ✅ Upgraded O-Rings: Made from Viton, a temperature and chemical resistant rubber compound, and much more robust than traditional o-ring materials.
