What is the diameter of the 1/4 outlet in mm?

I didn’t measure it but I’m guessing it was 6.35mm because it fit the pipe supplied with the fridge freezer perfectly. A brilliant piece of kit!

Will this work in reverse or is it one way only? I want to feed a garden tap from the fridge supply pipe.

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. 👍

is the screw thread 15mm

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.
