QUESTION: What does CSST look like?
ANSWER: CSST is often coated with a yellow, or in some cases, a black exterior plastic coating. CSST should NOT be confused with flexible gas appliance connectors - the product that joins a moveable appliance to your home or building's gas supply line. (back to top)
QUESTION: What is the difference between yellow-jacketed and black-jacketed CSST?
ANSWER: CSST has been supplied in the U.S. with a yellow polymer jacket since the early 1990s. The yellow color is utilized to help identify the piping as 'gas line.' Around 2005 the first black-jacketed CSST product was introduced. The black jacket signifies a protective jacket design, which provides a level of lightening arc protection to the CSST (tubing) underneath. Black-jacketed CSST is referred to as 'arc-resistant CSST' and has met a baseline lightning arcing test incorporated into the CSST product performance standard (ANSI LC 1). Both yellow and black CSST are commercially available. (back to top)
QUESTION: What are the benefits of flexible gas piping?
ANSWER: Besides providing greater durability, CSST is flexible, allowing it to be snaked around walls and through obstacles with fittings needed only at the ends of each run. Reducing the number of fittings is beneficial as each additional joint needs to be fitted and checked for leaks. A CSST gas piping system has less joints, and therefore less potential leak paths.

QUESTION: How many homes have CSST?
ANSWER: In the U.S., about 300,000 new and remodeled homes per year have CSST installed; that number is about half of the number of new homes built each year that use gas for heating and cooking. As of 2012, about seven million homes in the U.S. had CSST installed. Since 1989, approximately one billion feet has been in stalled in residential, commercial, and industrial structures.

QUESTION: Where is CSST located in my home?
ANSWER: CSST is usually routed beneath, through and alongside floor joists in your basement, inside interior wall cavities and on top of ceiling joists in attic spaces or connected to fixed appliances such as water heaters. (back to top)
QUESTION: Is CSST safe to use in my home?
ANSWER: Like all approved gas piping systems, CSST is safe when properly installed. CSST must be installed by a qualified professional and in accordance with the Manufacturer's Design and Installation (D&I) Guide, including bonding and grounding of the system. (back to top)
QUESTION: What are the effects of lightning on CSST?
ANSWER: Lightning is a highly destructive force. Even a nearby lightning strike that does not strike a structure directly can cause systems in the structure to become electrically energized. This power surge can potentially puncture a hole in CSST and cause a fire. (back to top)
