Reed offers CSST (corrugated stainless steel tubing) Tubing Cutters in different models for cuts with the outer plastic wrapper jacket on or off. They fit 1/4” up to 2 1/2” CSST flexible gas piping. For cuts with the jacket off, Reed recommends the RT15T1 and the RT15T2 which feature a special nylon roller design allowing square and central cuts for optimal flaring in various CSST systems. The TC1.6QCSST is a great option for cutting CSST tubing up to 1 5/8” with the jacket on. For cuts of 1 1/4” up to 2 1/2” with the jacket either off or on, Reed recommends the TC2QRGT.
