$177.00 /each

Frequently Bought Together

Product Overview

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.

  • 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

Answer: 
1/2" should be plenty, unless you are running over 100ft a gas line. The connectors at the stove are probably 1/2" anyways, and a lot of people use 3/8" hose to connect from the shut off valve to the stove anyways. I originally had about 15ft of 3/8" copper hose running directly to the outside tanks. and it worked just fine.

Answer: 
There are many variables involved with sizing gas piping which must be considered .
1) BTU requirements for the appliance .
2) Length of run
3) Are there other appliances involved
4) Most importantly : Will I be adding appliances to the line at a future date ?
You may well save yourself later expense by running 3/4" piping and being done with it .

Answer: 
There is no single answer to your question. It depends on line length, gas pressure, and the model of the stove. Look in your local gas piping code, or better yet, have a plumber install the line. You should not be messing with gas lines unless you are prepared to educate yourself extensively about the safety implications of it.

I can tell you that when I installed a natural gas BBQ in my yard years ago I used 1/4 inch copper pipe as a feed and never had a problem with the anount of gas, With that in mind, I would suggest erring on the side of caution and use 3/4 flex, for the few extra dollars it will give you adequate gas supply and some to spare. When you buy a new range they reccomend using either a 1/2 or 3/4 i.d. flexible supply line so you will be covered either way.
Last but not least, go online and do a search for a gas pipe size calculator, you can enter all your variables and it will give you the absolute correct answer. Read Less

Yes, it can if the requirements are followed. Any pipe will require protection with a sleeve(conduit) and in some situations, the pipe sleeve will need to be vented.
Building codes require that gas piping runs that come in contact with earth or other material
that could corrode the piping be protected from corrosion. Piping installed beneath (underground)
or within the slab of a building must be encased in a nonmetallic water-tight conduit
that is vented. Fittings and couplings are not permitted when HOME-FLEX® is installed underground.
HOME-FLEX® should never be buried directly underground without a conduit. To route
HOME-FLEX® tubing underground, it must be protected within a nonmetallic water-tight
conduit that is at least ½" larger than the outer diameter of the CSST tubing. Fittings and
joints are not permissible in such runs; the run must be one unbroken line of tubing.
For outdoor underground installations, the annular space between the CSST and the nonmetallic
conduit must be sealed to prevent entrance of moisture, dirt, debris, and insets.

Answer: 
Hi Marcos, -- CSST can be routed underground only if it is run within a non-metallic conduit. Building / Safety codes do not allow CSST to be direct buried. We do make "Wrapped Pipe" which is available in the diameter that you need. Wrapped Pipe ca be direct buried. However, it is only carried in the western stores.

It would appear this product is not suitable for direct burial applications without encasing it in another pipe, as such, does home depot sell a suitable replacement for direct burial applications for Natural Gas? Black pipe not an option. Thanks

Rated 3.3 out of 5 by 8 reviewers.
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 Don´t Even Think I would suggest you don´t even think about buying this product. My licensed and certified installer could not get it to seal. I checked other reviews, maybe some of those folks got a better product and were successful. I am among those that are disappointed in the product. April 23, 2015
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
Rated 5.0 out of 5.0 by Corners...No Problem This is the first time I’ve used this in place of steel pipe. It’s clean, easy to handle, snakes easily, flexes around corners well and is easy to see after installation. I used it to install a tankless water heater. Just drilled my holes and snaked it thru, There was no cutting, sizing and fitting nipples, Just put a connector on each end and you’re done, you don’t need to buy additional fittings. If you’ve worked with black pipe before you will be amazed at the time savings as well as keeping your hands cleaner and making it easier to work. A great and quality made product. December 3, 2013
Rated 3.0 out of 5.0 by leaks the video shows a pair of channel lock pliers tightening nut. I used a 1 1/2 inch wrench and it still leaked. January 10, 2015
Rated 1.0 out of 5.0 by Unstoppable leaks. Avoid at all costs. This seems like a great idea. Easy to run, fewer fittings to leak, simple installation. It sounds great, but the reality is this product is junk. Fewer fittings, yes -- but every one of them leaks. You eventually get the leak to slow down, so you're only losing about 1 psi every 10 minutes (starting at 15 psi), but it's enough to fail an inspection. Besides, who wants leaky gas pipes? My black pipe holds 60 psi overnight with no discernible loss in pressure. I don't expect as much from CSST, but it should be possible to hold 15 psi for an hour. The instructions say: "Step 1: Gradually tighten fitting until leak stops." Problem is, the leak doesn't stop, no matter how much you tighten. Sometimes you tighten and it gets worse. Then you have to take apart the fitting and reassemble. Do that 5-6 times on a single run of pipe and you've eliminated all the time savings over black pipe, but you've spent way more on the stainless steel. Not worth it. Run your gas in black pipe, or get another brand of CSST elsewhere that can make a proper seal. September 19, 2014
Rated 5.0 out of 5.0 by Excellent product and very easy to use Used this product to run an additional line for my gas grill unit outside. No more propane tanks! This Tubing was very easy to bend, attach, and run t the desired location. BE USRE YOUR GRILL IS THE RIGHT TYPE PROPANE OR NATURAL GAS! There are replacement units available for your type of grill. Check your grill manufacturer. Very simple product to use. Have someone that knows how to shutoff and bleed your line before installing a coupling tee! December 3, 2013
Rated 5.0 out of 5.0 by Great alternative to black iron For those of you who enjoy threading iron pipe, this review's not for you. This high-quality flexible stainless steel pipe is easy to use, but follow directions carefully for cutting and putting the fittings on the ends. Also -- I'm surprised that the directions don't include warnings to include electrical bonding in the installation plan. All local codes in the Philly area require bonding flexible stainless gas lines. December 6, 2013
