flexi straight on to iso valve

[CAESAR32]

Hey is it ok to screw a flexi straight on the the male thread of an isolation valve?

 

[Burnerman]

yes you can...you may find however that it may be difficult to get a perfect seal because the isolator has tapered edges to accept an olive....this gives less of a flat surface to grip the rubber washer in the flexi.
Do keep an eye on it for a while!

Yes, but not ideal. The end of the valve will be slightly tapered to accommodate the olive and this can cut into the flexi washer.

Great minds and all that

 

[CAESAR32]

Do most people use this method though

 

[Burnerman]

A better method - if you want to use a flexi - is to have a stub of copper pipe just after the isolator, and use a flexi that has a compression end on it.
I tried your method ages ago with some Ikea taps with flexi connectors....all was initially fine until the tiny droplet two days later!

If you really, really have to use flex's, you can get them with integral shut-off valves.

No problem, just file a flat face on the edge the washer is going to sit on. Although you've probably done it by now

I have often used this method on 15mm fittings without problems. It doesn't always work on 22mm fittings though for some reason.

If the valve is chrome, why not screw one of these on, giving you a flat surface for the washer?

Although, depending on location and visibility, it might look a bit daft

Just been looking at a few things on the Toolstation site, and discovered that there is now an adaptor to allow you to fit a flexi connector straight onto an isolation valve.

What will they think of next?

Good point. At about the same price of a chromed rad valve. Must get my boxful of tails on ebay

that 15mm to 3/8 one would be well handy!

I've put them straight onto (15mm) isolation valves with no issues at all.
