Q:What is the maximum angular joint deflection, assuming each pipe is angled in each hub?

Answer This Question
A:Â Thank you for your inquiry on the NIBCO 4 in. PVC DWV Hub x Hub Coupling Fitting. The socket cups are on an angle (1 degree, so 1/2 in. on a side) to generate mechanical flex when properly solvent cemented, which holds the joint under some pressure during curing. But a pipe system should be properly supported in any case to prevent any flexural stress or bending-moment stress on all the components therein. If you have additional questions, you can reach a NIBCO Technical Services Advisor, M-F 8am - 5pm EST, by phone at (888) 446-4226.
