Products / GAF Master Flow Versa Caps

Master Flow Versa Caps are GAF's adjustable aluminum pipe caps for rooftop chimney flues, hot stacks and B-vents. A screwdriver-adjustable clamp fits the cap tightly to the pipe, and a positive draft design helps reduce the risk of clogging. Four models (3050, 5070, 7090 and 9011) fit single and double wall metal pipes with outside diameters from 2 7/8 in. up to 10 7/8 in. (nominal 3 to 10 in.).
