has approx. 4 turns from full closed to full open. Have a look at the
Radiospares/Electromail web site on http://rswww.com/, either do a search
for 'plumbing, valve, needle' to see their selection or look at part # 262-0713.
This is a foot mounting needle Vv. that takes a ¼" OD Cu pipe in & has a
3/8" ID hose fitting on the output.
Anyone whose had anything to do with electronics or radio/tv repair
in uk over the past 50yrs will know of RS but they've now got a very good
selection of reasonably priced (well for uk anyhow !) plumbing bits & pieces
in stock - including 54mm T pieces, end caps & bends & AND THEY TAKE
PLASTIC !!!!!!!!!! The needle Vv. was selling for UKP10.46 + tax + pp this

- Thanks for all the responses.
After about 20 phone calls, I eventually found a place here in
Australia that could get a 3/8 needle valve in for me. It ended up
costing $25 and has a 3/8 female bsp thread either side. What that
means is you can put whatever attachment you want either side - I've
got a 3/8 compression fitting one side (to take the copper pipe) and
a 'tube nipple' the other, that a plastic hose can slide onto.
The place also has heaps of sizes in heaps of different fittings - I
also got a combination of fittings that will allow a digital
thermometer with a 3mm probe to be put into the top of the head, all
with a compression fitting so it can easily be taken in and out.
Anyway, now I have all the bits for the column - now I've just got to
organise the boiler (Jan, expect a phone call soon!)
Oh, the place I got the fittings is called:
and is a hydraulic hose and fittings specialist - they are at Waycol
