Flexible Connector

[AS3]

I have a flexible water connector for a water filter system that connects to a main (stopcock) 3/4 inch male thread .

The male end is correct (1/2 inch), please see attached picture, as this fits the water filter system, but the Female end is also 1/2 inch and is too small. I need the female end to be 3/4 inch to fit the 3/4 inch male thread main (stopcock).
Can anyone advice me where I could get this in the UK.

welcome to the forums. any plumbers merchant should be able to sort you out, you need a 15mm to 3/4 flexi like this

from tool station for £2.42 item number 54390

Thanks so much for the link.
I have been to several Plumber Merchants already so I am surprised, but grateful that you have found it so quickly.

Just to confirm that this is definitely the correct one. Is the 15mm male thread, the end I have circled in red?

Hi AS3

Just to be clear what you are trying to do. Am I right in thinking that you want to connect the female end of your flexi directly to the stopcock?

I am assuming that this is a 22mm compression stopcock from which you have removed the nut and olive?

The reason that I ask is that you can't rely on that thread to be 3/4 BSP male. 15mm compression fittings are almost always 1/2 BSP" threads, but the same doesn't apply to 22mm. For example, if your stopcock is an old Kuterlite one (very common older make) then the thread will be too fine pitched.

BTW in your pic above, the red circle is round a 15mm compression end, but if you remove the nut and olive, then it will be 1/2 male BSP. However, depending on what you are connecting on to, you may need to file the face flat, since it will be machined out to take the olive.

PS - a pic of the two things you are trying to join would be very helpful.

Thanks for your help. I went to ToolStation and they had the item number 54390 in stock.

I thought I had found the solution until I realised that it is not a 15mm thread I need but a 12mm thread, which is why it has been difficult to find. So to clarify I need a 12mm compression end, after removing the nut and olive on one end and a female 3/4 on the other.

Maybe I can use the flexi item number 54390 if I can find a coupler that can reduce the 15mm compression end to a 12mm compression end?

I have some 12mm x 15mm compression fittings somewhere. Pm me if you get stuck and I will see if I can find one for you
