A brilliant piece of kit! **Q: Will this work in reverse or is it one way only? I want to feed a garden tap from the fridge supply pipe.** A: I can’t imagine why it wouldn’t. You may have to put the filter on the opposite way around (I’m not sure how the filter works) but other than that so long as you have the correct mating ends on your fridge and outside tap- it should work. 👍 **Q: is the screw thread 15mm** A: Hello, I am not sure there is such thing as a 15mm thread but this item is 1/4" push fit x 15mm push fit which means you can join a 15mm OD pipe to a 1/4" pipe and we have recently changed the way it looks so its one piece as we were having reports of leaks coming from where it screws together but we have now eliminated that.

Easy to put on and seems to have worker 100%. Just does what it says on the tin ### ⭐⭐⭐⭐ Easy to fit *by R***F on 27 July 2017* Does the job and no leaks. Simply just push in to pipe and your ready to go. An improvement would be to have an isolater on connector so you dont have to turn off mains supply when you change fridge or fridge needs repairing. But would recommed installing an isolater before installing this coupler --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/49728904-15mm-pipe-to-1-4-fridge-water-filter-pipe-adapter](https://www.desertcart.co.uk/products/49728904-15mm-pipe-to-1-4-fridge-water-filter-pipe-adapter) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-06*
