How To Make an R410A Flare for a Mini Split AC Unit Installation

Note that you should use Nylog ( amzn.to/40jcSVU ) if possible in order to improve the quality of your flares and flare connections. Simply put a small amount on the cone of the flaring tool before flaring and then a tiny bit more again when you make your final flare connection. Good luck on your flare!

When using an eccentric flaring tool, it is important to first read the instructions. The required extension varies per manufacturer. For example, I own a Yellow Jacket eccentric flaring tool (Model 60295). The instructions specify a 1 mm extension, which is less than 1/16 of an inch. In contrast, your video instructs a 1/16" to 1/8" extension. If I used that length, I would risk splitting the copper. Also, as others have noted, you should put a drop of refrigerant oil (e.g., Nylog Blue) on the cone tip before flaring. The refrigerant oil acts as a lubricant and reduces the torque needed to make a flare. It also helps to extend the life of the tool.

Professional HVAC guy has "egregious" in his vocabulary, has invested in quality tools, and reads the instructions. Hack says "teflon tape will fix this flair good 'nuff!", spells flare wrong, overtightens it and doesn't bother with a vacuum pump. Then gives a bad review of the equipment he bought online because it failed. Good skills and experience will always win. Also, excellent video skills; good job getting the focus correct and showing the cone rolling the flare through the gap.

I'm a YouTube junkie, this camera angles, resolution, lighting, magnification, is spot on! 👍

Purchased: August 2023 - still works GREAT!I youtube.com/post/UgkxxsUnXhGsSJLim_XnMHyQK0u3XVaW-… live in a studio and during the summer it gets scorching hot - really old building with no ac units. I can’t express how EASY it was to install. This unit has been a life savior during the summer and some days during other seasons where it can still be a bit warm at night. In this small place is my friend, a husky, poodle mix and myself. We need AC - lolI don’t use the dehumidifier option - I’m not sure if it will leak in my house, since I did not install the small draining hose that came with it. May look into it late but I don’t worry about much humidity in the apartment. I don’t understand why the negative reviews since all things mentioned, I personally did not find issues with. Definitely worth it!

Good video. Another really important tool I started using is a flare gauge. To make sure they are perfect every time. Helps a ton.

That eccentric flare is fantastic. Back in the day when the family had an automotive custom business, we did a lot of steel brake lines.. All we had was the straight push cone flare tool. This is SO much better.

Pretty good video Benjamin. As a retired Commercial HVAC owner. I have struggled with flares for many years, till I discovered Rigid makes a double flare tool set. Ridgid 33927 Specifications: •  Model No.: 345/150DL •  Size: No. 345 w/No. 150 Tubing Cutter and case kit (Rather expensive but worth it) Believe me when I tell you when you make double flares, you'll never go back to the old tools again. It forms the tubing inward first with a small button, you remove the button then use the sets flaring tool. I never had a leak after that, and it is good for thousands of LBS Johnson Refrigeration / Happy Retired.

This was another excellent video tutorial that you have presented. I’m getting ready to order the R410A and pipe cutter.

I did some copper flaring years ago, on a project. What a pain. I now see what I was doing wrong. I did finally get it, but not without many tries. Thanks

Good video. I've always had trouble deburring the tube. I like the way you raised the burr with needle nose first and then cut off the burr. I'll keep that in mind for next time I'm flaring a line.

Holy shit, I thought it was weird that you're using high end electricians needles then I come to find out, you're that electrician guy I used to watch. Great content, dude! 👍💪

Really excellent video, perfectly demonstrating the difference between a good flare and a bad one. This is very helpful.

As a newbie I have watched several of these videos trying to learn how to flare copper piping. After several attempts and several failures I finally watched this video and within five minutes was making perfect flares. Thanks for the help! Sub’d

Well done. I have made flares in the past and did not think of using the needle nose or the knife. Learned from you, thanks.

as i was taught 40 yrs ago and still teach.stick pipe thru block the thickness of a nickle,slithly more .highly recommend tork style blocks.too many tough guys wrecking flares.

Thank you I think I'll be making my own flares on my line set 👍😁

Nicely done. You don't mention the shoe, but we can see it makes a convenient place to place the tool. Thanks for sharing

AaaaaaAAAH! geez! that "factory standard" flare makes my skin crawl. My split machine came with a set of tubes with a similar finish. I bought a set of tools and practised on copper tubing until I much perfected* it, then I proceeded to assemble my AC unit. After a few years of the split being in use I had an AC professional take a look at it, they did a leak sniff for insurance reasons, he found no fault except some astethic choices I made. AFAIK 14 years later it was still working. *Perfected = the tool set was considerably cheaper than yours; lacked the torque-stop and eccenter. The tube clamping part of device always left a small pinch mark on tube above the flare. The pinch mark did not interfere with the nut so it did not matter much.

Great clarity and detail. Could you do one on replacing windscreen wiper inserts?
