Product review (5 stars): Easy install
The manufacturer is Pro-Flex and they have a free safety certification at www.proflexcsst.com this will be necessary if you are installing yourself and need the certification to clear your permit. The line is rated for 5 PSI working pressure but is tested up to 40 PSI static test. Most low pressure natural gas meters run at 1/2 lb of pressure so this is not an issue. This piping is very durable and can make a 90 degree turn in just 8 inches. This 3/4 inch piping is recommend for up to 170K BTU max. I also recommend using the yellow natural gas nylon tape versus traditional pipe dope for the threaded connections, it just works better in my opinion. Well I hope this helps.
