3/16" SAE double flare unions - hey stubby !
Posted: Sat Oct 28, 2017 10:56 am
The Autozone couplings/unions from two different manufacturers are no more than 5/8" long and made of brass. The tubing nuts have less than 3 turns of engagement (!) when first tightened by hand. That is true using commercially flared tubing, or tubing flared by me and my trusty 40 year old NAPA/New Britain flaring tool.
Online parts look equally short.

I expected Russel or FedHill or someone to offer couplings with proper longer engagement, and possibly made of steel.
No such luck.

I can appreciate potentially better sealing using a brass coupling, but the short engagement is going to be on my mind for the first panic stop for sure.
Has anyone found longer 3/16" SAE couplings ?
