According to its maker, TracPipe CounterStrike corrugated stainless steel tubing (CSST) needs fewer fittings to install than traditional black iron and has a conductive black jacket that eliminates any need for additional bonding to prevent damage from lightning. The company claims the heavy jacket also makes the tubing more crush-resistant and easier to straighten than other CSST products. It comes in seven sizes. Prices range from $4.50 per foot for 3/8-inch pipe to $29.50 per foot for 2-inch pipe.
