HVAC - liquid line fittings

Post by dzak83 » Fri Jan 25, 2019 10:21 pm

Hi,
I need one 3/8 fitting for the liquid line connection but can't find it anywhere (like in the attachment). Maybe I looking for the wrong name, so how is it called?

I saw names like aeroquip fitting, chatleff fitting, tailpiece, tailpiece with telfon o-ring but can't find it to buy anywhere. Any ideas? Where are you getting this stuff?

// Yes, it's for refrigerant R410A. Yes, I know about nitrogen purge.

Thanks!

Also, I am seeing mixed comment about flaring for HVAC application, that it won't hold the pressure but then some guys are using torch or oil. Is flaring accepted for refrigerant lines?

You're likely relegated to an HVAC supplier for what you're looking for, while it might look like any other 3/8 fitting, the threads are probably wildly different from what you would find in the plumbing world. Heck, even 3/8 fittings in the plumbing world often don't match up. I'd take the part with you, in hand, to the supplier and match it up with what they've got.
If the women don't find you handsome, they should at least find you handy.
