Alrighty, so today we are on a install here: got the air handler we're doing a flush application, so we'll be cleaning out these lines here today we are using the hillmore uh pipe cleaning kit. Here we have our our gun here with nitrogen hooks too tip of our gun. We have this threaded fitting, which allows us to use a variety of sizes and a little box. Here we have our actual foam fittings that we can shoot and clean through the lines different sizes there.

Then we have our little mesh baggie that we stick on the outside catch these on the way out, so we don't lose them and then we can reuse them. We're getting ready to actually use the gun here step. One is we want to de-burr both the copper lines, just use a reamer deburr the inside, so that way um our foam pigs, that's what they're called can slide right in there. These fittings just slide right over.

They have these um hose clamp type deals that you can finger, tighten those just slide right over the copper and then you can finger tighten the hose clamp over the copper, we'll do the uh the three quarter. First, what we're going to do is we're going to take our gun here. So just screwing on like that, this little chamber slides back. It allows us to get our properly sized foam pig here slides into the chamber, and then the chamber closes like so then we take our nitrogen attached to our nitrogen tank and we're gon na screw this bad boy on, like so we're going to turn on our Nitrogen here and we are ready to basically punch it through.

So it's just a matter of pulling this little trigger here like so. The pig should be out of the chamber now gone to our baggie and then we're gon na go on the outside and show you what it looks like from the outside. Okay, we are back outside. I have the bag on both the lines here.

As you can see, the other three-quarter foam had already popped through now we're going to shoot through the 3 8 line. Now i am going to hold on to this just because it does produce quite a force or pressure and then we'll be able to see it come through that line and voila we got the uh three-eighths, the three-quarter. Our lines are clean and we are ready to braise in thanks for watching our video if you enjoyed it and got something out of it.
