Sam with Kalos Services and HVAC School does a field demo with the new Hilmor lineset cleaner. The Hilmor lineset cleaner requires you to use nitrogen to force foam pigs through refrigerant lines, cleaning up residual oil and refrigerant as the pigs work through the tubing.
Included in the Hilmor lineset cleaner kit is a threaded fitting, which allows you to use a variety of foam pig sizes depending on the tubing diameter. The Hilmor lineset cleaner also comes with a catch net to collect the foam pigs at the end of the line.
Before cleaning the line set, deburr the copper to give the foam pigs a smooth point of entry. The fittings slide right onto the line, and you can finger-tighten the hose clamp on there. He attaches the lineset cleaner gun by threading it on.
Sam starts with the 3/4″ pig, which he slides into the chamber of the gun. Then, he hooks nitrogen up from the tank and discharges the pig by pulling the trigger. The pig comes out at the other end and stays in the catch net. Sam repeats the process with the 3/8″ pig through the liquid line, thus cleaning both lines.

Very cool
Great idea I just hope there is never a kink in the wall
Great product
So can I use this for cleaning a r22 system that I have to convert to a 410a ??
What good is this? Its not removing all the oil.
waste of money …i just spray the the garden hose in it till it come out the other side
So besides the price tag, whats the difference between what people are doing now to clean the lines?
This is really stupid. Just more useless shit to sell to us. So what happens when there’s a kink in the line behind the wall you can’t see? And nitrogen alone does this exact same job. What the nitro doesn’t pick up, the drier will.
I like the idea of these but I'd use a normal regulator on the nitro so you could hold the pressure up.
No thanks, liquid flush has worked okay for me so far
Way awesome! Pro flush is a pain in the ass at times.
What does triple vac achieve if you the pass decay test below 500 microns on the first vacuum?
Did they buy out the Pipe Wiper? Or different patent?
Where’s the blower from that AHU?
Small over braze or copper would stop that plug. Not sure what it achieves. Change your drier blow through with ofn . Triple evacuation then good old fashion vac
Awesome 👌🏾
👍
Wish it had a ¼ plug for mini splits
I would be nervous of the foam plug getting stuck like in a slight kink or a fitting. Not to mention different size pipes in the other.
Nice ,I think I would flush first then introduce the pigs?🤔
Thanks again for the videos!

Stay safe.
Retired (werk'n)keyboard super tech. Wear your safety glasses!
Does this eliminate the need to flush, or would I do this in addition to flushing? (Changing out an r22 system with 410a system)
What about 90° fittings?
nah
That's gonna be a no for me.
That’s pretty interesting! I would be very nervous about one of those foam plugs getting lodged in a lineset though. I guess you could go try and blow it out the other way. Do you feel like they could get stuck on a kink, braze bb, fitting etc or do you think they can pretty much always be forced out?
And if it gets stuck because the lineset installer kinked a bend 10 years ago? Or a service tech repaired a leak halfway in the lineset by brazing a 3/4 piece inside of a 7/8 line? Are the plugs soft enough to squish through these scenarios?
