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.

  • Saves time - 60% time savings vs. steel pipe fitting
  • Cleaner and easier to handle than black steel pipe
  • Bends around corners eliminating need for additional joints and fittings
  • Use coordinating HOME-FLEX CSST fittings
  • Great for seismic areas - ridged pipe often leaks after even small tremors
  • CSA and IAPMO certified
  • Installers should be certified to install HOME-FLEX CSST, to become certified visit

Rated 3.5 out of 5 by 24 reviewers.
Rated 5.0 out of 5.0 by Great price, easy to work with I ran a line out to my grill using this pipe. It's very easy to work with and bends easily. Attaching the ends was also DIY friendly so no need to hire a plumber to run your gas lines. Just make sure everything is tight and check for leaks. July 9, 2013
Rated 5.0 out of 5.0 by Piped entire home with Alpha-Flex I hard piped from my propane tank down the side of my garage wall then, to my grill with black pipe (required outside) and then, inside the attic with 1/2" Alpha-Flex over to my water heater, and heating units. I also installed a manifold in the attic for any future needs. Doing this by myself, it took only two days to complete and was very easy to work with. July 29, 2013
Rated 1.0 out of 5.0 by Not Compliant! I bought, as a certified installer, your Home Flex brand of CSST gas pipe for a new home install. I invested $800+ dollars and 2 days of my time to install everything in the new home. Loudoun County Plumbing and Gas inspector says it isn't compliant with code and is making me tear it all out and put in a different brand of CSST that has the ANSI# listed on the pipe. Now I have to buy all new pipe from another supplier. So now my time, money and work is more than doubled. I have $800+ of Home Depot product that will be trashed for non-compliance. If your going to use this pipe, buy a section and take it directly to the inspector FIRST! Do not install this product first. March 5, 2014
Rated 5.0 out of 5.0 by Great quality, easy compared to iron I'm a fan of flex stainless, but mind your p's and q's with this stuff. Remember to bond it (electrically) when you install. If you don't know what this means, don't use it. Seriously. Also, consult standard tables of gas pipe diameter and carrying capacity. This 1/2" line doesn't have a huge capacity to run three different appliances at once. Used properly, this stuff is magic, and can save you hours of install headache. December 6, 2013
Rated 1.0 out of 5.0 by Disaster Used this for gas line in my new construction house. Inspector said our county won't accept them because they don't have the rating printed right on the pipe, even though it's in the instruction manual. I had to tear it all out and replace it with similar stuff from Lowes. Home Depot was very good about working with me and I made them aware of this problem. Just check with the county before you use this!!! April 15, 2014
Rated 1.0 out of 5.0 csst not compliant with code according to baltimore inspector junk connectors had more leaks to just two appliances on one job then i had in two years (approx. 50 houses) using ward flex junk junk junk March 14, 2014
Rated 5.0 out of 5.0 by Great product and system First you MUST read the online instructions they cover sizing, assembly, routing, securing and bonding. Plus the manufacturer has videos. Very easy to install. After the local Gas company found 23 leaks in the old black pipe system, I redid everything in Home-Flex except the fist 20 ft from the gas meter which I re-doped and re-assembled the original black pipe. As for leaks absolutely none in the Home-Flex - tested at 10 psi for 1 hr with compressed air. Just passed final inspection from the Gas company, purged lines - no leaks - gas is back on. Let me clear up a couple of incorrect reviews - the black O-ring does not seal the fitting - it is there to keep gunk from getting under the jacket - see instructions for using tape if you lose the o-ring. Also replacement brass retainer ring, o-rings and fitting non-metallic gasket are available at HD both online and at stores that carry Home-Flex. A tip that may help you make a leak free connection the first time - I took a metal file to each cut end, removed any burs or uneven cuts before assembly - if you look at the instructions burs are a common reason for a leaky connection. Finally the 1 inch by 3/4 inch manifold in my photo is only available by special order from HD - you won't find it at the stores or on the web site. September 23, 2014
Rated 1.0 out of 5.0 by CSST Great... Home-Flex Horrible! STAY AWAY!! I purchased the Home-Flex CSST system to run about 75' of new gas line under my house. I spent the next 2 weeks trying to fix the leaks. If you torque the nuts well past the 62 ft-lb requirement, you can get the leaks to a minimum. I'd typically lose 1/2 psi per day if I started at 15 psi. It's enough to get you past an inspection, but not quality work. Yesterday I finally gave up and pulled it all out and replaced with Pro-Flex from Lowes. I've had the pressure at 15 PSI for almost 24 hours now and it hasn't changed at all. With the Pro-Flex system I didn't have to re-do a single connection; they all worked the first time. There seems to be enough complaints about Home-Flex that Home Depot should really pull the product so more people aren't wasting their time on this product. November 16, 2014
