Where can I buy durable hoses for carpet extractors online?

I’m currently losing my mind because my second "heavy duty" extractor hose just developed a pinhole leak right in the middle of a job. It’s the worst water spraying everywhere like a broken hydrant while I'm trying to look professional. Honestly, I’m done with the cheap retail stuff that cracks if you look at it wrong.

I’ve been scouring the web for something that won't give up on me after three months. I spent a whole night tumbling down the rabbit hole on Alibaba and, honestly, I was actually pretty impressed with the listings there. Seeing the actual factory specs and those bulk industrial grade rolls made me realize how much we usually overpay for rebranded junk. They have these reinforced, wire-bound options that look like they could survive a tank.

But since I’m not exactly looking to order 500 units right now, where do you guys go for high quality, single replacements? I need something that’s actually flexible but won't kink or burst when the pressure's on.

Gonna lose it if I buy another dud. Is it better to stick to the big name detailer sites, or should I be looking at those industrial chemical supply shops instead?
