Our HVAC Vanstone Flanges
Vanstone flanges are formed directly on the pipe, bending a 1/2″” lip at a 90º angle toward the outside of the duct. This 1/2″ flange holds an angle iron ring on the pipe, still allowing the ring to spin freely. The rings can then be easily aligned with other vanstone flange fittings or duct and bolt together, forming a very tight and strong connection.
