HOME-FLEX Corrugated Stainless Steel Tubing or CSST is great for installation of gas appliances. CSST easily snakes into attic and basements areas, around corners and bends and through walls. Much easier to work than steel pipe, uses fewer fittings and weighs a lot less too. Certification through manufacturer is recommended before installing CSST.

Cleaner and easier to handle than black steel pipe
Bends around corners eliminating need for additional joints and fittings
Use coordinating CSST fittings
