About Master Flow™ Oval‑to‑Round Boot ‑ 90 Degree

This Master Flow™ 90-Degree Oval-to-Round Boot helps transition a 6 in. oval pipe to a 6 in. round pipe or a 6 in. insulated flexible duct. It is an efficient use of space due to the fact that it allows duct work to be run between wall studs. Insulate duct work for system efficiency and comfort. Always seal duct work seams with code-approved mastic, sealant or duct tape (not included).
