The ACRK-STARTER kit is the perfect way to set up a shop with the ability to repair aluminum A/C lines quickly and profitably. It's also a great alternative for a shop to have a system on hand to splice new OE lines that come in two sections. The kit consists of a full SLK-2 with both tool and a full set of jaws, as well as a scaled-down assortment of seven total tube-to-tube repair unions. Once the amazing utility of this system is realized, the kit can be easily replenished with tube-to-hose and block-off repairs.
