Flaring and Preventing Leaks on Ductless Systems

[@seanstinebuck4890]

AHAHAHAHA!! Definitely done it 3 times in a row before!!

[@artificialintelligence734]

As an auto mechanic, when reassembling an engine for example, service manuals instruct you to lubricate bolt threads, then torque.

Just had to do some leak repairs on a Daikin VRF. Had 10 different flares to repair and some leaks on the ref-net wyes. Torqued all flares,24 hour standing pressure test proved i got all the leaks. Vacuum down to 250 microns...only rose to 293 microns....added 52lbs of refrigerant and she's purring like a kitten. For those that don't know....on a VRF....you have to put the equipment in recovery/Vacuum mode. It opens all the stop valves, EXV's and allows you access via pressure and Vacuum to the whole system and its piping.

Thanks for these great tech videos! You always make a great presentation! iuts like actually being in the learning room with you!

I love the channel! Just read the Weekly email and absolutely loved it! Awesome to know that you are a brother in Christ! Happy thanksgiving!

I had an idea that he mightve been a brother in the LORD but now it is confirmed. Definitely appreciate this channel by grace

One tip take time cutting the tubing use light pressure on the wheel to reduce the burr and deforming of the tubing

[@chrisdeanndavison3626]

9:40 This whole concept is even more important when brazing copper. The piping may stay together due to friction in the joints, but once you apply heat, if the pipe doesn't want to be in that position, it will come flying apart. Really bad once there's silver solder on the joint and it gets flung on you. Learned this the hard way years ago!

Buy a Fenix PD36r Flashlight and a kydex holster. Ive been using Fenix led flashlights, and headlamps, for 10 years now and they are great for the price and also make life so much easier…especially when you have a headlamps when in dark attics and basements! You have your hands free and the light is directed right where you need it to be. Rechargeable 18650 or 21700 batteries are a must! Cheers

Three times in a row???!! Omfg haha! I don't flare too often but when I do I almost forget the nut most times....

[@joffrecueva5662]

This guy and greg are my go to for hvrac👍

[@Hubjeep]

1:28 I torqued a 1/4" flare with Nylog and it kept turning until it spit out the tube! Maybe the Nylog provided too much lubrication resulting over-torque?

[@kellyklotz1744]

How do you feel about the prepaid flare fitting that you just push the copper into

[@chrisdeanndavison3626]

19:02 Using Crescent wrenches for everything isn't a great practice. True, but I have a pair of Craftsman that combines an adjustable wrench and vice-grips. When you squeeze the handle, it tightens the jaws just ever so slightly and makes up for the sloppy fit Crescent wrenches normally give you.

[@aidanbuchanan2090]

You wanna link that is there a specific name for a wrench like that? Sounds interesting

[@chrisdeanndavison3626]

@@aidanbuchanan2090 Just do a web search for "adjustable locking wrench". I believe the Craftsman one is the "Extreme Grip Adjustable Wrench".

[@darmarek]

What do you think of FlareSeal®

[@paulgaras2606]

I would like to see some content from HVAC school on VRF/VRV systems. I know you’ve done some limited stuff in the past but it’s been kind of rep driven. I’d like to hear what Kalos and other HVACschool contractors have experienced with VRF.

[@jonn093]

Love this shit. keep it up!!!

[@ryanmalin]

If the flare connection is going to be inside a wall, I cut out the flare and solder it. This way I know its not gonna leak

[@chrisdeanndavison3626]

How are you able to solder to the factory flare fittings built into the mini-split?

[@allnoyz1414]

My 2 cents on torque specs - you triggered me on the light specs for smaller tubing... GM 3.9L V6 spark plug torque spec is 132 in/lbs - that's 11 ft/lbs. That's awfully light-feeling when you do it. I just can't do it without an extra 5-15 degrees just for good measure.

[@dealecrabr9425]

crows foot flair nut kit is the only way to go, all other wrenchs deform the brass nut by making 2 point contact,,,,, crows foot alows for use of the torque wrench which i do after using the regular flair wrench to snug up,, but im old and wore out,,,cant do much anymore

[@timkirkpatrick9155]

3/8 or 1/4in torque wrench with flare crows foot.

[@dorhocyn3]

45°, versus 37 1/2° or something ?
