As you know, the new mechanical code requires R4.0 insulation on all split system line sets. In response to this change we have decided to stock the new GelBlack line sets. In addition to meeting the new R4.0 code requirement these line sets feature a new tear resistant GelBlack insulation that is UV resistant making it easier to install. They come packaged in bags which take up less space and less waste on the job site.  The ends are a flat crimp ensuring the line set is clean inside every time.  The GelBlack comes in 25′, 35’, & 50’ lengths.


We are also stocking the new (50’ only)  TwinGel white minisplit R4.0 line sets. The TwinGel insulation is fused together making minisplit installation much easier.  It is also tear and UV resistant.
