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 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 homeflex.com
  • CSST is generally for indoor use; however, it can be used outdoors and/or underground with very specific parameters. Please see the HomeFlex Design & Installation Manual on this site and/or at homeflex.com for details. If considering an outside underground installation, we suggest you check out Home Flex UNDERGROUND products.
  • Not to be used with Home Flex UNDERGROUND fittings.
  • CSST tubing operating pressure: 25psi (max 125psi). Operating temperature range: -20f to +200f. Stainless steel melting temperature: 2400f.
  • HOME-FLEX Corrugated Stainless Steel Tubing (CSST) flexible gas piping material must be installed by a qualified installer who has been certified in the use of the HOME-FLEX gas piping system. Certification can be completed by reading the System Design and Installation Manual and registering with Valencia Pipe Company to obtain a qualified installer card. Register at homeflex.com; "Get Certified" option.
  • Some areas of the United States do not allow installation of CSST for fuel gas piping systems. It is the installer's responsibility to check and understand all codes governing the location of installation prior to installing HOME-FLEX CSST. See specifics in the HOME-FLEX System Design & Installation Manual available for viewing or download at homeflex.com.

    Q:Can this product be buried In the ground ?
    by|Jan 9, 2023

    Answer This Question

    A:  The yellow Homeflex csst would have to go inside conduit to pass code. Homeflex does make an underground version.

    by|Jan 11, 2023

      A:  Hi, Eddie. Not directly. It can be used in-ground, but it must be in a watertight non-metallic conduit at least 1/2" larger than the OD of the CSST, and it must be vented, and there can be no fittings inside the conduit. Suggest you look at HOME-FLEX UNDERGROUND PE pipe and fittings instead. Check out our Design & Installation Manuals at homeflex.com/resources.

        Q:Can this be ran to a gas dryer for operation?
        by|Dec 16, 2022
        1 Answer
        Answer This Question

        A:  Hi, Veet - CSST can be used to hook up directly to non-movable appiances. However, any appliance that may be moved (like a dryer, range, etc.) should terminate prior to the appliance and a gas appliance connector used to make the final hook up. Please see our CSST Design & Installation Manual at homeflex.com/resources.

          Q:Can CSST be used to connect two separate runs of iron pipe? And if so, how should it be bonded?
          by|Dec 13, 2022
          1 Answer
          Answer This Question

          A:  Hi, Allen - Yes, you can use CSST to join 2 runs of iron pipe. You can follow the bonding instructions in section 4.10 of the Home Flex CSST Design & Installation Manual available at homeflex.com/resources. Basically use a 6g or heavier copper wire from the black iron or csst nut back to the grounding buss bar in the electrical enclosure. This can be done from the closest point of the gas distribution system to the electrical enclosure.

            Good pipe, but poor factory cut ends
            Overall the pipe worked well. The connections were easy to make, and the flexibility really made for an easy install. I needed to connect an outdoor gas grill, and a fire pit table. The 3/4 inch fit the bill, and what I needed was exactly 25 feet. The one issue which prevented me from giving it 5 stars, was the condition of the factory cut ends. I hoped they were accurately cut, and burr free. That was not the case. I therefore needed to spend an extra $40 for the pipe cutter to get a clean cut. If it's expected that you must purchase this at the same time, you should be made aware of this.

              I took a chance on this one because the other big box store didn't carry it in 75 foot length. This is not a bad product if you are meticulous in cutting the tube straight, round, and without burrs. Follow the directions to the exact detail. Make sure you crimp the ring so its a circular shape and does not spin easily in the valley. On one end of the tube I polished out a burr with my dremel grinding wheel. I had to tighten each nut anywhere from 50-70 ft-lb. Both terminals under pressure passed the soapy water test, so I'm happy enough.

                This was a good product. Saved me time and headache working with the black iron. It might have costed a little more than the Black Iron. I deducted a Star because the Home-Flex website (where you have to go get certified) was horrible with broken links. They also advertise parts they don't make any more (like the Tee) which was very frustrating as I planned what I was doing based off of what they said was available on the website.

                This is the best stuff since sliced bread. Takes all the headache of running black pipe out of the picture. Very easy to use and move a line if needed like I had too. Took longer to drill the holes than to pull the line.

                Works good enough and its nice that you can get certified from them so that you can show your inspector if he wants to know who installed the pipe. The only thing that I dont like is that the yellow plastic sleeve cracks easy. Making the install look messy. Unsure if code allows for painting or removal of the plastic yellow sleeve, or if you can just paint the yellow plastic sleeve. Simple enough to connect. Use a copper tube cutter.. pliers to crimp.. and you are set.

                Really made converting my back yard barbecue and fire pit a breeze. Make sure you install a shut off valve between the tubing and hose. All hoses leak gas under even low 1/2 pound gas pressure Just ask a welder. Don't do this if you aren't 100% sure what you are doing. Double check all connections for leaks. To change from propane to Natural Gas use a jet kit or you can just drill the propane jets 30% larger. Exactly like drilling carburetor jets. Never leave the gas valve open if you're not using the gas. I always close the gas valve off and let it burn out at the barbecue or firepit. Then I go close the valve on the barbecue and /or fire pit.

                Do not pay attention to the negative reviews of this CSST. If you have an issue with leaks after installing this product it is more than likely becasue you did not follow the instructions and that is no fault of the manufacturer. On every fitting that you purchase there is a sticker that reminds you to follow the instructions and those instructions are included with every fitting! Not to mention several online videos and a free istruction booklet right next to all the products! I installed 25 feet to feed a gas dryer and it was 100% leak free the first time (pressure tested for 24 hours to verify). I have no issues with this product and if your looking for CSST that works then look no further.

                  Easy install
                  When my wife and I decided to remodel our kithcen my wife wanted a gas oven. I was not looking forward to removing the bulkhead in our finished basement just to run the black pipe. When I found home flex I got excited. The whole install took only two hours. I fished the csst through the bulk head and connected both ends with no leaks. Were is the easy botton?

                    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.
