NEW Hilmor Tools with Scott Mieras

After the demos at AHR, many people had questions about the lineset cleaner’s efficacy on severe kinks as opposed to the relatively neat angles of the demonstration copper. In the demonstration at the symposium, Scott brought a demo rig with much more tightly kinked lines and showed that the pigs made it through just fine. He also added water to the system, and the pigs displaced it very quickly.
“Pig” is the industry term for the plugs that you send through the line set, and the term originated in the oil and gas industry. They come in various sizes for different line set diameters. Even if the pigs don’t make it to the other side, a blockage indicates that the line set has severe issues that need to be addressed. If a pig gets stuck, you can blow it out the other side and make it return to the starting point. You may also be able to use each pig multiple times if they don’t suffer major damage on the first use.
You can get the Hilmor lineset cleaner and pigs at many local supply houses. If you can’t find the lineset cleaner or related accessories in your supply house, be sure to talk to the distributor and let them know that you’re interested in the product and want it on the shelves. Hilmor will be selling the pigs in packs of 10 for each size.
DiversiTech also has a new SWOOSH drain gun that was launched at AHR (the SG-2 double-barrel model). The SG-2 drain gun uses two 20g cartridges and offers 2.5x more volume at the same PSI as before.
Another new Hilmor product is a portable sheet metal scoring tool. That tool allows people to create cross breaks in the field quickly and easily. Hilmor also has a reversible magnetic hex driver with easily changeable bits. It uses steel of the same grade as impact hex sockets in the field. The driver was developed with longevity in mind, and it has been tested as much as possible to make it strip-proof.
