I put in a new tankless water heater and decided to use this product for the gas line. Ended up being one of the worst decisions I have ever made. The fittings don't leak to the point of smelling gas...but when the system is pressurized to test at 5 PSI(tubing rated pressure) or at code pressure(10 PSI) every fitting leaks. It does not matter how much the fittings are tightened. Most codes require that when performing a gas system pressure test, the pressure must hold 10 PSI for 15 minutes. With these fittings, I was loosing 1-2 PSI in 15 minutes. You won't detect the leaks with a cheapo $20 gas detector. But if using a good quality leak detector, every fitting will have a leak at the back side by the yellow jacket. I wasted about $200 on the tubing and fittings. I read all of the instructions and watched the installation videos before doing this project and certainly did want it to work out. I'd rather be safe than sorry so I'm ripping this stuff out and going back together again with regular steel piping. Which by the way, I found no leaks on the connections where I did use steel pipe. One last thing, if you want to purchase replacement sealing washers for the fittings they aren't available in the stores. Home Depot may want to consider a different vendor for CSST.

Rated 3.0 out of 5.0Â by Zane I have worked with this in the past
The previous review isn't exactly fair. I am sure there could have been user error. I have worked with this on many home in my past. Heck, I even have the scars to prove it. (This stuff can get ya if after you cut it, very sharp edges.)
It is much better than running black pipe all over a house. To get this to seal make sure you put enough Teflon and Teflon paste on before trying to screw the piece in.

Rated 5.0 out of 5.0Â by Rudy Quick and easy
This product is much more easier to use that steel pipes. The flexibile corrugated tubing allows you to quickly perform an installation. You do do not have to have exact lengths, bends and connectors. The end fittings require additional work but overall it is faster and easier. Getting the ring tight so that it does not move caused me to bend the circular corrugated metal tubing out of shape that I had to correct - the end must must be circular so that it is matches the soft circular gasket for a seal. Make sure that to get to the 62 lb ft. of torque in installing the fittings because this forces the flexible steel tubing into the soft gasket in the end fittings for a seal - check for leaking especially around the yellow jacket after installation. Installation was easy. Please note that Home-Flex and Alpha-Flex are from the same manufacturer. My local HD had Home-Flex tubing and Alpha-Flex fittings with no sign that you can use them together.

Rated 5.0 out of 5.0Â by HAWGMAN10 Fastest way to install gas pipe
CSST made my project of installing a gas firepit so much easier. Instructions were detailed but glad i read because i had to install in electrical conduit to run to patio. Would recomend for those who want to add gas accessories.

Rated 1.0 out of 5.0Â by AwesomeO Leaks despite tightening completely
Despite warning from other reviewers, i purchased this, and it is a very bad quality product. The seal doesn't work. Regardless of how much torque I added, there was still leak. I tightened to the limit, and the leak still wouldn't stop. I'm going to order pro flex system. Don't waste your money on this.
