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.

Can you cut with regular pipe cutter

Asked by Bob April 1, 2021
1
Answer

Hi, Bob - We highly recommend the use of a tube cutter as shown on homedepot.com. Here the link to copy/paste in your browser: https://www.homedepot.com/p/HOME-FLEX-1-2-in-1-in-O-D-Pipe-Size-Corrugated-Stainless-Steel-Tubing-Cutter-11-TC-02125/204767432 Not quite sure what "regular pipe cutter" means, but if it's a rotating blade that is tightened at each revolution around the pipe, that should work. Thanks.

Asked by MikeDrums February 27, 2021
1
Answer

Hi, MikeDrums - CSST is designed mostly for indoor use and, as such, doesn't have much UV protection. If used outdoors and/or underground, it should not be exposed to sunlight and is suggested to be in a watertight, non-metallic conduit (like PVC). It can be used to connect to appliances so long as it is done in accordance with our Design & Installation Manual available by copying/pasting this link: http://homeflex.com/downloads/HOME-FLEX_Installation_Manual.pdf. Thanks.

can this be used outside of a garage wall can it be used on an exterior wall outside

Asked by Jimbo February 13, 2021
2
Answers

Hi, Jimbo - Even though CSST is primarily for indoor use, there are a few provisions for its use outdoors. Check HomeFlex.com for the CSST design & installation manual. First, if used outdoors, it should be protected from the sun and crush by putting it in a non-metallic shield (PVC) where the ID of the pipe s at least 1/2" larger than the OD of the CSST. Further, there should be no fittings inside the sleeve. Also, the ends of the sleeve should be closed to make it watertight. If buried, it should be done per local codes (burial depth, watertight sleeve, etc.). Should you have any questions, please contact our Technical Service Department (Jon or Dave) M-F 8a - 5p Pacific time @ (661) 257-3923 x 1010 or 1026. Thanks.

Can this be run under crawl space?

Asked by Peter February 3, 2021
1
Answer

Yes it is possible to route CSST in a crawlspace as long as you do it in accordance with the HOME-FLEX System Design and Installation Manual and all of your local codes. http://homeflex.com/downloads/HOME-FLEX_Installation_Manual.pdf Above is a link to our manual. You can copy and paste it into your browser.

Hi, Goltmier - It is not sold by the foot. 25' is the shortest length available.

This for underground

Asked by Richard December 14, 2020
1
Answer

Hi, Richard - No, for the most part, CSST is for indoor use only, not for direct burial. Home Flex Underground is great for that. The only way CSST can be buried is if it was in a non-metallic water-tight sleeve (PVC). Check out the Underground Design & Installation Manual for details on that product. http://homeflex.com/downloads/HOME-FLEX_Underground_Manual.pdf

Does this have the same capacity as 3/4" black pipe?

Asked by Jack November 29, 2020
1
Answer

Hi, Jack - No, 3/4" black pipe would have more flow capacity than our corresponding 3/4" CSST. For instance, if you look at our HomeFlex CSST Design & Installation manual (available at HomeFlex.com), page 49 chart 7.11 shows the flow capacity of schedule 40 metallic pipe. A 10' run of 3/4" would yield enough gas to support 360k btu/h. Conversely, if you look at page 44 of the manual, table 7.1 shows a 10' run of 3/4" CSST to be 200k. So, even though the ID sizes are very close, the flow through each of the different types of pipe is very different.

What is the maximum working pressure?

Asked by Bob November 20, 2020
2
Answers

Hi, Bob - The specification operating pressure is 25 psig. The max tested pressure is 125 psig. You can check out our website at HomeFlex.com and view all other product details. http://homeflex.com/downloads/HOME-FLEX_CSST_Tubing_Submittal.pdf. Thanks.

Is home flex compatible with tracpipe?

Asked by Fixed November 17, 2020
1
Answer

Hi, Fixed. CSST tubing has various standards, but "dimension" isn't one of them. Therefore, manufacturers' measurements are minutely different and, in some cases, aren't compatible with other products. We recommend that if you use Home Flex tubing that you also use Home Flex fittings. Same with Tracpipe.

How do i connect 1/2 in tubing to my meter when the meter has a 1 in female connection point?

Asked by Ry September 25, 2020
2
Answers

Hi, Ry - There are ways of reducing dimensions, but a larger concern is that it appears CSST was used in a below-ground application which CAN be done with several significant provisions. No direct burial. Since not much info is provided in your inquiry to provide meaningful suggestions, would it be possible for you to call our Valencia CA office? I'm Dave and can be reached at (661) 257-3923 x 1026 M-F 8a-2:30p. In the meantime, I invite you to check out both our HomeFlex Underground and CSST Design & Installation manuals. Here are the direct links to copy/paste: http://homeflex.com/downloads/HOME-FLEX_Installation_Manual.pdf http://homeflex.com/downloads/HOME-FLEX_Underground_Manual.pdf. Look forward to hearing from you so we can assist.

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.

Response from VPC, Home-Flex ExpertJan 7, 2019
Thank you for your review Tyler. Thanks for letting me know that the Tees are still on our website. I will have them removed. ValenciaPipe

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.

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.
