Rated 5 out of 5 by from Very good product I bought these as my so called need build home did not have any isolation valves under the bath and I was planned Ng on changing all my taps over. They are pricey, you can probs get same with plastics, but went with metal to ensure higher temperature threshold . These were great to use, so uch simpler to get metal compared old school style. The function of cutting the pipes and being able to remove the copper pipe all together made changing taps a doddle, they are great as isolators bit also due to the way you install them actually makes working with pipe easier for taps as you can remove it all together. No leaks so far and it has been a few days, time will tell longevity, but I plan to remove bath panel and open and close them and wd40 to prevent any seizing. PS test these first on a scrap piece of copper pipe first and fill it with water like a bottle to see how it works before cutting into you main pipe, as mine was leaking but turns out I was not pushing the copper pipe in far enough .

Rated 5 out of 5 by from Does the job Simple solution for adding additional radiator on central heating system. Can't comment on reliability so marked 4 for that, but it's allowed us to add a rad, whilst not having it and so we can add it later. Not the cheapest, but hopefully you are paying for quality

Rated 5 out of 5 by from Replaced leaking plastic ones Had issue with the plastic version of these leaking up through the stem after being off for long periods. These likely to be more reliable I hope, with all brass construction. Also have decent max temperature unlike the worryingly marginal 65degC of the plastic ones. Pretty heavy compared to the plastic (and a few mm's shorter). NB. Insets and collet clips are ESSENTIAL but are not supplied with.

How does one disconnect this fitting and will it cope with multiple disconnections (my plinth heater seems to need disconnecting and flushing annually).
Asked by: Gorf27

Can you use this valve with chromed copper pipe and can it be released easily without using a tool.

Asked by: Marrich

Okay for Copper pipe connection without additional insert?

Are these suitable for copper piper in & out with no requirement for additional insert for perfect seal? Thanks

Has anybody used these valves on chrome pipes. I want to fix these to my shower feed pipes which are external. And would look tidier than the standard ones.
Asked by: blackbeltuk
Speedfit fittings can be connected onto chromium plated copper pipe if the chromium plating is completely removed to the full depth of the fitting. To ensure maximum grip, the fitting of a collet clip is recommended. It is not possible to connect Speedfit fittings to Stainless
