Isolation valves for 15mm copper pipe

[Amp David]

Just wanting to know what size the thread is on one of these valves. Its the type of valve you turn with a flat blade screwdriver to turn on and off.

When I say the thread, I'm on about the compression nut

 

[telectrix]

think it's 1/2" BSP, or 3/4" BSP

 

[antimatter]

Is it for a shower or something?

 

[Amp David]

No just wanted to know what size the threads are.

 

[telectrix]

ask your friendly local plumb center

half inch BSP

 

[telectrix]

thought it was. at least some measurements have not gone foreign. British Standard Pipe, about the only British Standard that is still British!

15mm is 1/2" BSP and 22mm is 3/4" BSP

ask your friendly local plumb center

Always find them over priced, Plumb Center IMO has always been expensive B&Q can be cheaper than them

 

[telectrix]

i find the opposite. plumb center and electric center are the same company. i deal with both, tho' not much with plumb. i try to leave the wet work to the drip boys. b&q sometimes cheaper on a wenesday, 10% off with my old gits card

Thanks all for your help

Sorry but that isn't true, 15mm is slightly bigger than 1/2 inch and 22mm is shorter than 1 inch, and you would need to use the likes of this for the 15mm Yorkshire Kuterlite Straight Tap Connector 626 15mm x ½" - NoLinkingToThis, Where the Trade Buys

And this Yorkshire Kuterlite Straight Tap Connector 626 22mm x ¾" - NoLinkingToThis, Where the Trade Buys for the 22mm.

And screwfix / and mainly toolstation now are cheaper than both of them.

 

[Amp David]

Toolstation are the cheapest now. This Tradepoint tosh at B and Q is Screwfix in a different building.

sorry but that is true, im sure UNG knows 15mm is bigger than 1/2inch and 22mm is more than 3/4", sure he also knows the 15 and 22mm refer to the pipe in question and the 1/2". 3/4" refers to the thread profile, ie "British Standard Pipe" thread.

 

[antimatter]

Sorry, i don't understand your point.

 

[telectrix]

don't understand last 2 posts. orig. Q. was the threasd size, nothing to do with the pipe dia. 1/2 inch bsp, end.

 

[antimatter]

I was just correcting UNGs' point that 15mm is 1/2" BSP and 22mm is 3/4" BSP.

He thought they were the same thing / size, I was pointing out, that they are not, (as anyone who has tried to connect 15mm to half inch and 22mm to 3/4 inch will know) XD

 

[telectrix]

see what you mean. why did we ever let the suits get us into the completely flawed, inaccurate metric system anyway?

 

[pmac10]

maybe im missing something, Antimatter, a 15mm pipe will connect to a 15mm slot valve (op) the threads on that slot valve are 1/2" BSP threads (op), the same when using 22mm pipe with 22mm slot valve which uses 3/4" BSP threads, i think i know what you mean now about trying to connect 15mm pipe to old 1/2" pipe, are we now on the same level?
