I have a hose for my heater circulator and I need more steel lines for it and I’m completly blanking on how to verify the size of the connections on each end of the hose short of going to Home Depot and trying to screw it in to a bunch of different sizes.
Help a dude out who’s still recovering from turkey coma
Npt is based on pipe ID
compression is based on OD.
Calipers are a really handy tool. Even the cheap plastic ones…

Only other thing I can add is the thread count. Swagelok makes a handy thread tool that you can easily identify any threading on bolts. We use them a lot having to deal with companies that use metric and others standard threading.
Here’s the link:
Make sure your getting the right fitting.
MNPT &FNPT only connect usually to equipment.
I believe you have a JIC fitting. Which is hydraulic hosing.
Does the fitting have a nipple or flat?
Use a ruler or tape measure if thats all you have

How about a picture next to a pencil or a lighter?
It’s probably not 1/8” that’s real small, it’s the connection size for automotive grease gun hose. 1/4” is what everyone’s first cls was plumbed with. 3/8”And some 1/2” is common on air brake systems. 1/2” is what everyone’s last cls was plumbed with.
I hate those ones, the General 132ME is better for the price IMO
…but that’s four times the price!
at $2.10 each those looked like a cheap enough option to have one everywhere (saturate your local universe…so they precipitate on demand).
still wondering why Amazon decided to feed it to me in espanol.
Most likely 1/2", maybe 3/8". A pic would help
