HOME-FLEX CSST saves you time and money with easy and flexible installations or additions.

More and more contractors and plumbers are using yellow HOME-FLEX CSST in and around construction sites these days. Not only because it’s safe and easy to use, but because it’s readily available at DIY home improvement and construction warehouse locations. It is also available at select plumbing and HVAC wholesale houses across the country.

CSST was developed in Japan in the 1980s as a safety improvement over rigid black iron gas pipes that often failed and started fires during earthquakes.The flexible nature of the CSST system allows it to handle seismic activity without leaking gas. Sales of CSST in the U.S. began in 1990 with approximately 100,000 ft. More than 800 million feet of CSST gas piping in approximately six million homes has been installed in the U.S. since 1990.

The main attraction to CSST is that it’s flexible and relatively easy to install when compared to standard gas piping. HOME-FLEX fittings are the easiest to assemble in the industry, no complicated series of discs, gaskets and o-rings; just a brass retainer ring and a single non-metallic gasket. It’s no wonder it has become such a popular product. So much so, the next time you swing by a construction site, chances are, you’ll be seeing HOME-FLEX yellow.
