I have a trivial question. I messed up half the thread on the vapour port of the recovery cylinder I use to stock up my solvent in between runs. I think I can use a long female female coupling then a reducer then a 1/4 npt to jic bit (or directly a reducer if the female part is long enough).
However I’m a bit confused by those imperial threads and while I thought everything was in 1/4 on my CLS, 1/4 jic and 1/4 FL seem a tad smaller.
So my question is:
If I’m using 1/4 jic tubing and my recovery cylinder is 1/4 fl-m should I chase a 1/8 (+/-9,5mm) npt female coupling?
I’d like to avoid ordering unusable parts from far away.
Thanks
I’m on holiday so I can’t take a pic of my rig ATM but I do have a pic of th f up cylinder.
I have a pretty basic 1lbs Chinese CLS with 1/4 line, 1/4 npt parts.
Tank is supposed to be 1/4 fl-m but 1/4 npt is too big. Outer diameter of the thread is more or less 9,5mm wich I assume is 1/8". That’s where I’m confused why call it 1/4 fl-m when it’s smaller that 1/4 not. I’m wondering if there’s more subtilities with Imperial thread.
I don’t know if it makes more sense between my lack of knowledge and my terrible English.
The problem is that if your vapor port threads are messed up and you cant properly connect your hose, that an adapter will also not properly thread to your tank vapor port, no?
Probably but I’ve still have half the thread ok. So I hope to be able to find a long female female bit that could grip on the ok thread. That’s why I’m trying to understand what imperial size I’m after.
Damn I had no idea there was so much differences between threads. I thought everything was straight and that diameter, connections and eventually “teeth” specs would differ. You sirs get me a bit of reading. I’ll dig into that.
Thanks a lot
