For some time, interest has grown about the ability of CSST products to withstand lightning energy.  Most homes affected by lightning are directly struck by lightning. Alarmingly, there has been an effort NOT to test CSST products ability to survive lightning damage. We resist such efforts.  If you would like to see actual direct strike lightning testing from an independant labratory, we invite those eligible to click on the button to the left.

Some have said there is no reasonable expectation that things in a home are are safe from lightning. To that we remind all, only gas plumbing in such a scenario is carrying an explosive.
