The E-Z Flange Jr. Spiral Pipe System has a 5/8" flange roll formed directly on the ends of the spiral pipe and fittings. Since the flange is part of the pipe and fittings, it adds rigidity and there is no chance for leakage. With no protrusions in the air stream to disrupt the airflow, the E-Z Flange Jr. Spiral Pipe System is much more efficient than any other self sealing system.

The E-Z Flange Jr. Spiral Pipe System is assembled by applying a gasket to one flange, mating the two flanges together, and attaching the barrel clamp. The E-Z Flange Jr. Spiral Pipe System is sealed so tight that it out performs both ASHRAE and SMACNA Leakage Class 3 Testing. There is virtually no leakage at the transverse connections (test data available).
