You can use the Hilmor lineset cleaner by itself or behind a solvent. The kit is neat, easy to carry, and comes with a thorough set of directions. You can insert the pig into the launcher, which comes with various adapters for many different tubing sizes. (We recommend reaming the edge before attaching the adapter to the line set.)

We recommend using a new pig every time, especially if you use them behind chemicals. The pigs are very consistently manufactured, and they come in various sizes. They also come with a catch net, which holds the pigs on the other side of the lineset.

You’ll find that your lineset cleaning jobs are a lot more thorough when you start using the Hilmor lineset cleaner.
