Connecting to 1/2 inch female thread on flexi tap connectors

[XanderHarris]

Hey, what is the best way of connecting to the 1/2 inch female thread on a flexi tap connector? I know a service valve will do it, but I could do to put two service valves before the mixer valve so don't realy what/need two more before the tap.

Put one of these on the pipe.

Or in end feed

That's curious, it looks like the second one has a left hand thread. I think they must have flipped the image!

Are they called number 3's? Do they look ok with the over valves being chrome do they not do them in chrome?

 

[Whitespirit66]

Don't think they're called 3s. They are available in chrome if they're on show.

A lot of merchants use manufacturer-specific codes as a generic system:

Yorkshire:

• 3 - male iron
  2 - female iron
  12 - elbow

Conex:

• 302 - male iron
  303 - female
  401 - elbow

etc.

The OP is correct in saying a copper to male iron adaptor is a number 3.

OP, what exactly are you trying to do?
The threaded nut normally goes on the theaded tail of a tap.
If you want compression both ends these are available from all good plumbers merchants.
