Works like it should. It's a pipe, it carries gas (or whatever), and it's flexible
I like it!

Once you have this flixible gas line, you can do the replacement yourself
Same price as offered at my local HVAC wholesaler. ...
Alex Carswell✓ Verified Purchase•November 16, 2017
Same price as offered at my local HVAC wholesaler. I bought this here because it came with the threaded termination fitting and a female fitting for the other side. Most of these flex lines don't come with the female fitting when they are sold at HVAC wholesale houses. Note: This flex line is coated, which is code required for almost any application - don't buy an uncoated flex line - they are prone to fail and can cause a gas leak!
Worked out great for my gas feed into a tankless water heater

Worked out great for my gas feed into a tankless water heater. I have it connected to a Duda stainless gas shutoff valve. Used Gasoila PTFE coated plumbers tape in 4.3 mil thickness made for stainless to stainless connections to keep it from binding up upon install.
