Eastman 0437118 Stainless Steel Corrugated Water Heater Connector, 3/4" FIP x 3/4" FIP, 18" Length, Red and Blue

I asked for stainless; I got copper. I asked for a pair; I got just one. I asked for 18"; I got 12". I asked for pipe threads at both ends; I got a hose-clamp fitting on one end. And doesn't Bezos have a space program? Stay back!

Perfect for connecting a water heater. Very flexible material will not kink like a copper flex line.

great fit

Easy to hook-up, color coding is a nice touch
