TracPipe® CounterStrike® is a flexible stainless steel piping system used for natural gas and propane installations. CounterStrike® is currently in use for gas piping systems in single and multi-family residential as well as commercial and industrial buildings. CounterStrike®‘s superior corrugated tubing coupled with AutoSnap® fittings combine to make the best CSST product available. CounterStrike®‘s full range of sizes (3/8″ to 2″) and proven reliability make it the first choice at all residential, commercial, and industrial job sites. CounterStrike® is accepted throughout the US and Canada. It can be run through buildings in the same locations where rigid pipe materials have traditionally been used with a fraction of the threaded joints and in a fraction of the time required for installation. CounterStrike® was designed with inner diameters that are very close to black iron pipe and offer the industries’ highest flow rates, which can often result in using a smaller tube size resulting in significant cost savings. All TracPipe® CounterStrike® CSST products are listed by CSA under the ANSI LC 1 Standard.
