Cobra Head Reducing Elbow 5" ID to 4" ID
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. Temp rated at 250-275F.
To make clamp installation easier, remove the locknut, align the clamp while holding in place, and screw on the locknut to capture the first few threads.
