Features
- Product Specification 33FT 1/2 inch gas pipe: inner diameter 0.48 inches x outer diameter 0.63 inches (12mm x 16mm). Therefore, our 304 stainless steel corrugated pipe can provide a flow rate of up to 100000BTU/hour, and comes with 2 Male Adapter Fittings
- Application Scenarios Gas pipelines are used to connect any indoor liquid propane or outdoor natural gas application to gas supply pipelines, such as gas stove pipes, fire pit pipes, generator pipes, grill pipes, water heater pipes, compressor pipes, etc. And provide sufficient airflow for larger devices. Meet the diverse needs of customers in various scenarios
- Flexibility and Safety - Stainless steel corrugated pipes have flexibility and can be cut into the size and length you want. They are made of 304 stainless steel corrosion-resistant material and have a 0.079 inch thick UV resistant yellow polyethylene protective cover on the surface
- Installation Instructions It can be embedded behind walls in concrete or drywall systems as needed. It is also suitable for underground installation. Please note that natural gas pipelines should not be buried directly underground without conduits. In order to lay pipelines underground, they must be protected within non-metallic watertight conduits that are at least half the outer diameter of CSST pipelines.

This stuff is really good. Being made of stainless steel, it's impervious to moisture, won't rust if put underground, and difficult to break even if you do bother it. Way outperforms Pex or steel gas lines. No rusting out, hard to damage... That said, if you use it for a high volume gas feed, it will whistle, because the inside tube is corrugated, and any gas flowing through a corrugated tube causes a whistle effect.. I tried it for my outdoor firepit and the noise drove me crazy, so I redid the project with yellow gas-rated Pex tubing (which is smooth inside) the stuff is a LOT more expensive (well the fittings are, not the Pex) and now my firepit is silent. But for general gas piping, this stuff is the best!!

Chinese junk. Returned and picked up US made product. You dont want to mess around with gas. This was not marked with any size. physically it was comparable to 1/2in vs the stated 3/4. Its 10 meters in length - that's why its 33ft(actually 33.7). Ends are preinstalled, which is a problem if you need a different size. Ends were also pressed onto the CSST jacket - this is a major problem for grounding. Very disappointed.

Appears to be a great product. Needed 22 ft of 1/2" for natural gas line to bbq grill. While there are no instructions with the tubing there are several clear Youtube videos on how to cut the tubing and trim to fit. Fittings provided were brass, accurate and threaded perfectly on 1/2 NPT. Much easier to use than running black pipe and eliminated multiple pipe fittings. Pressure tested 100% first try.

I ran this under decking. Total length was just under 20 feet. The fittings are totally different than anything you can get at supply stores or big box retail stores. Flex pipe csst fittings are difficult to get right no matter what brand you're using and these are no different. For final success, I had to cut as smooth as I could with a twirl around pipe cutter, then file the cut end until it was smooth and flat. Before calling it all good, I installed a shut off on one end and a gauge cap on the other and pressurized to 30 psi. It lost about 1 psi over 24 hours, and while not 'perfect', it was within spec, so good enough! Running it under the deck was the easy part after drilling the joists - it's very flexible and can do some fairly sharp bends. It's only supplying a 22" griddle, and for that it's working good and supplying the gas. For a short run like mine, the price was great! If the fittings were easier to get a good seal on I'd give this flex pipe 5 stars. I've encountered the same problem with name brand flex, too, so it's not just this brand that suffers from that deficiency. 4/5, and I would get it again, but only for short runs to save some money.
