IbergrifM3/8"-M1/2" UK Compression Adaptors Connector from 3/8 Inch to 1/2 Inch, Metal, Chrome, Silver

Bought as an adapter for under kitchen sink. Works as intended, easy to install and of good quality. No leaks as of yet!

Worked perfectly to fit my Water2 filter under the sink as it was a pain! Had to reduce the mains in to the tap tails and this solved the problem!

Good quality fit perfect

Nothing wrong with these items. Had to send back due to the fact that they are the wrong size " my bad" . Hence the return. The quality of the item is very high, it looks like high grade steel, and will be able to work in any plumbing area as a connection or conversion to fit another plumbing system.

If you have standard isolator valves, best use these for European 3/8 taps. It is easy and cheap.But if you really want to go all out you can replace the valves with 15 to 3/8 isolator valves for a clean look. I've done it but wish I didn't - takes too long, likely to flood house, likely to introduce slight leaks if you don't install properly, etc.Do I'd say go with these, cheapest and easiest route - don't forget to use the rubber seals and don't over tighten, don't kink the 3/8 tubes. Good luck.

I'd bought a Grohe kitchen tap, not realising they have 3/8" tails, so wouldn't connect to UK 1/2" isolating valves. Plumbers merchants only sell compression fittings that require you to fit a small length of pipe (or remove the isolating valves altogether), which I wasn't prepared to do. I was about to return the tap when I found these adaptors.Just screw onto the isolating valve (don't forget the seals) then screw the tap tail into the other end. Job done in under 5 minutes!

Purchased these for the Ibergrif M22137 Kitchen Tap - https://www.amazon.co.uk/gp/product/B083RXMH5PShame the tap doesn't come with them in the box but they fit perfectly, the price is great and delivery was super fast.

We had a tap with EU fittings and the push fit fittings were GB, these bridged the gap perfectly. I used a bit of PTFE tap on all the threads, attached them to the tap first then the pushfit attachment and boom. No need to over tighten, no leaks.
