4" ID Cobra Head - Silicone

4" ID Cobra Head - SiliconeCobra head elbows are used when clearance is extremely limited, such as when an air cleaner outlet is up against a firewall. There is no other way to make a really tight bend without losing air flow. How does the cobra head make such a tight bend without increasing turbulence? Because it flares out, creating more volume internally without increasing length. Use a cobra head anywhere a standard or short radius elbow will not fit. Five ply reinforced
