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.
Recommended clamps are 94100-0450 on the small end and 94100-0550 on the big end.
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.
