Welcome to the Bunnings Workshop community. It's fantastic to have you join us, and thank you for sharing your question about your Ryobi pressure washer hose.
I suggest bringing your machine to the store's special orders desk so that the team can make sure that they order the correct hose for your pressure washer. Please make sure to bring your hose as well so that our team can take photos of the ends of the hose itself. They can then send those pictures along with your order.
If you need further assistance, please let us know.
