Corrugated Tube

What is Corrugated Tubing?

A flexible tube called corrugated stainless steel tubing (CSST) is occasionally used to supply natural gas to residences and commercial buildings. If you installed a new natural gas device, like a stove or furnace, in your home, CSST, which has been in use since 1990, might have been utilized for the natural gas piping. Risk: Inadequately bonded and grounded CSST may cause fires in structures struck by lightning or natural gas leaks. CSST frequently has a black or yellow coating. Corrugated tubes' distinctive structural design makes them useful for a wide range of applications.
