Gas PipingQuestion 249 of 360
What best describes CSST used in gas distribution?
a.Rigid black steel pipe with threaded joints
b.A rubber appliance connector
c.Plastic pipe for underground gas only
d.Corrugated stainless steel tubing, a flexible listed distribution system installed per its manufacturer's instructions
Explanation
CSST stands for corrugated stainless steel tubing, a flexible, semi-rigid distribution piping system with proprietary fittings that speeds installation compared to threaded steel. It must be installed strictly per its listing and manufacturer instructions, including protection from physical damage and required electrical bonding. It is not the same as a short appliance connector or plastic underground pipe.
