Much easier to work than steel pipe, uses fewer fittings, and weighs a lot less too. Certification through manufacturer is recommended before installing CSST.

Rated 4.0 out of 5 by 14 reviewers.
Rated 1.0 out of 5.0 by Not in my house I am a master plumber with 15 years experience, this is worst product for the transportation of gas I have come across. I can't believe it was ever approved for sale to anyone. The fact that it uses a fiber washer as the only sealing point is mind boggling. I have used many different brands of CSST for gas and never had a problem, this stuff leaked at every fitting. I ripped it all out and went with a better product. October 4, 2015
Rated 5.0 out of 5.0 by Easy to do I needed to pull the pipe through tight space under the house and hook up my heater and oven. With Home Flex it went fast, its easy to put all the fittings on, its clean. You need to be careful not to cut yourself as the edges of stainless steel tube are razor sharp and don't forget to ground the pipe to avoid lighting damage. March 15, 2014
Rated 1.0 out of 5.0 by worst product I have bought at Home Depot. First, I can't believe that Home depot actually carries this junk as their CSST products. I bought two lines to convert my 2 wood burning fireplace, 100ft and 25 ft. You can't get a connection leak free with this junk, at first I thought that it was just me that I was doing it wrong, but after 10 different fittings and attempts I finally reach out to a master plumber, he came and said the same thing the gasket is made out of paper, the company called it fiber, but it's cardboard paper. He said in his 20yrs experience he has never seen a gas gasket made out paper. Unfortunately, one of the lines that I ran I had just closed the wall up so I can't bring it back to the store, What a waste of time, money and effort. I hope Home depot review this product and take it off their shelves before they ruin their reputation. Should have gone to Lowes. November 23, 2015
Rated 5.0 out of 5.0 by PSI RATING This information is from Home Flex. You can test it as high as 25 PSI for short durations. Most inspectors will test at 15 PSI (or less) for 5 mins. Working pressure rating is 5 PSI. November 15, 2015
Rated 5.0 out of 5.0 by Great Product! Installed a new gas stove and needed to run a gas line from my garage through the attic and into the kitchen. This tubing made the job so much easier than it would have been had I used black pipe. No joints were required. I simply connected the tubing to my gas supply in the garage and went through the attic and down through the wall to the new gas stove. I attached a shut-off valve at that point, and then connected the gas to my new stove. Piece of cake! I highly recommend! April 20, 2013
Rated 5.0 out of 5.0 by Not difficult to use when you follow the directions I had to replace a makeshift gas line from the previous homeowner. I installed the gas line under ground using plastic electrical conduit to seal the product from the elements. I used two 25 foot sections because I was only running the gas line 35 feet and could not see paying the extra money for the 75 footer and having to through away or store 40 feet of gas gas line. This meant I had to use two couplings and one union. After reading most of the reviews it appeared the biggest complaint was is the difficulty with getting a tight seal. As long as you follow the instructions you'll be fine. Do not cut the tubing with a hacksaw as it will give an uneven cut thus preventing you from getting a tight seal. Use a pipe cutter. Home Depot carries a wide variety. I went with the Husky Quick Tube Cutter costing $15.98. The only complaint or issue I have with the product is the plastic coating. I had to go around two elbows and the coating chipped off. June 15, 2015
Rated 5.0 out of 5.0 by Very nice product This yellow pipe made a very difficult job easy. Will use again if needed. December 17, 2012
Rated 4.0 out of 5.0 by Csst Tubing worked well. However I was very disappointed that the tubing came with NO ends. Just bare pipe. This required another trip to HD. If I had been informed of this I would have gotten adapters when I purchased the black pipe and fittings. Nothing was mentioned in the literature. August 7, 2015
