Connecting flexible tap tails to isolation valve

[jrtrrror]

Hi all.
Just discovered the flexible tap tails are too short to reach the isolation valves by about 60mm. When I did the same type of job at my house, I learnt that using a tap tail connector is better than connecting directly to the iso valve, with its sharp edge. However, these are too short to make up the 60mm difference.
So, can a I use a radiator valve extension such as this

I tried looking for longer 500mm tap tails, but no one seems to sell them. Well, there are placed on eBay and Amazon, but I worry about quality.

Anyone got any ideas.
Many thanks

Then just use a bit of copper the required size out of the Iso ?

Or just extend the pipe from your iso valves (using the iso valves nut and olive to connect) and then use a male straight fitting (1/2” x 15mm) if connecting to a tap flexi that has the nut and flat rubber washer end

They will be fine.

Get WRAS approved flexible tap tails form BES. Quality should be good. And if your tap tails are speedshit, then speedshit onto chrome is a no no.

Hi Cos. Did you mean replace the flexible Monobloc tap tails with your suggested speedfit Flexi tap connector. 15mm X ½"?
Forgive my ignorance, but I don't see how they would work. There appears to be no 10mm thread to connect to the tap and they are only 300mm long. The ones currently in use are 400mm long and around 60mm too short.

And to Best..
Was my suggestion doable? I've just noticed it reads 15mm x 15mm and not 15mm X ½". I'm confused by the measurements

15mm would refer to a compression or speedshit connexion. 1/2" would be a BSP threaded connexion as you would usually find on the isolators.

Hi. Thanks. Do BES do 500mm long ones? I remember seeing there site, but was unsure about the company.

I meant use a 15mm x 1/2” male straight.
The threads are actually 1/2” both sides, but one end has a flat face which will suit flat washer end of flexi.
Other end is for 15mm copper

Thanks, again. Does that mean my suggested 15x15 radiator tail would not fit the compression iso valve?
