Can anyone help me to identify a plumbing thread?
Here's a photo, the scale below is in mm:
Pipe diameter is 0.51" (13mm), a 29/64" (11.5mm) drill bit is a loose fit in the female fitting, a 15/32" (11.9mm) bit doesn't fit.
TPI: roughly 6 turns in 8mm (from photo) is 19 TPI.
Any thoughts?
Nigel
Just had a thought, the fitting that fits it is a gas fitting.
Nigel.
1/4" BSP without a doubt. Major Dia 0.5180" Minor Dia 0.4506 19 TPIBaz
Many thanks.
Any idea where I can get a parallel M-M in brass, preferably with a hex nut in the centre - like the body of a compression fitting?
Stainless would be OK.
BES don't seem to stock it.
BTW, soon after your kind reply, I found this:

Machine Mart do iron ones.
That's a Table worth printing and keeping in your box. baz
How about in black? BES code 6439 or galvanised 8641
