Air line fitting threads - calibrate me please

[Cenedd]

Just to clear up some confusion, I'm not fitting anything to metal pipes here and I'm not running hard line of any kind either. The particular joint...

BCRider Thanks for that. Quantifiable numbers and everything. I've not broken out the torque wrench but I think I'm definitely over that much.

I knew the answer in that I was aware it referred to vintage pipe OD's but by your own admission those no longer exist. Schedule 80 is "very close"...

I know. I get "If it ain't broke, don't fix it" but it does seem odd when (almost) everything else has gone metric and the nominal dimension...

Just started getting into the new money pit that is compressed air. Before anyone says it, yes it's mainly due to jealousy....I'm sure you understand!...

J Tiers Not just you. It's been odd over this side of the pond too. Wasn't long ago it was snowing, shortly before that it was 21°C out (70°F) and...

BCRider For what little it's worth, I had trouble flycutting a difficult piece. To be fair, mine was mainly mill scale but the HSS was blunt before I'd...

Hi guys. Just wanted to report back: mission accomplished. Tap turned up this morning. Procrastinated what I ought to be doing for work and ran it...

These are apparently by Profile and do see to be north of a hundred bucks and use a UNF thread. Bolts available (in the US - so hideous postage, import...

[Cenedd]

Ah, sorry guys. The thought it might need differentiating from a motor bike part never occurred to me.
mattthemuppet has hit the nail on the head...

I've been given a bike axle to fix. It's essentially a 3/4" rod with a spline and a 3/8-24 tapped hole at each end.
One of these (perhaps both)...

Yeah, same as your customer.....I'd send it to you! ...
