I knew without looking anywhere else that I would get what I want in screwfix and they were exactly what I wanted and would use you again they were the right size and will use screwfix every time I want anything as they have always got it in stock and if not in stock they will get it in for you

I would recommend these over any "copper, or brass fittings" John Guest Speedfix is the best on the market, I have used over 400 JG fittings of all sorts and NEVER had a leak or even a slight weep of any kind. Although 11 leaks on compression out of 37!!! Don't take the chance use John Guest, I have used it on old and new copper pipe with great success.
