Line set flare angle

benjamincall · 10-23-2009, 12:05 PM

This brochure from this Yellow Jacket distributor says LG mini splits use a 37° flare on their line sets. I talked with a first line LG customer support guy who tells me 45° is the appropriate angle. Can anyone share some first hand experience?

Here's the brochure from Kivlan:

I confirmed with LG that 45° is the proper angle for the flare. The fellow I talked with was unsure, so he referenced the LG training manual.

Yellow jacket is a BIG company and not likely to make mistakes, it is possible that LG's latest models are using the 37 deg flare but it would be in the install manual of the specific unit. Installers may need to own both flaring tools in the future.

The new ones are definitely 45°. Believe it or not, none of the literature for the LG units specifies the flare angle. You have to look in one of LG's training manuals to find that information. The Yellow Jacket distributor (Kivlan Group) confirmed. The 37° figure was something I found in newsletter from 2007.

While we're on the subject, which flaring tool do you use?

Buy one of these and you will love yourself. Does everything and never messes up a flare.
