Dundas Jafine MC6ZW Worm Gear Hose Clamp 6 Inch Galvanized

Product Description

The DUNDAS JAFINE MC6ZW is a 6-inch worm gear hose clamp constructed from heavy-duty galvanized steel. It is designed to secure semi-rigid and rigid aluminum duct to aluminum pipe fittings, elbows, and collars in residential and light commercial HVAC duct systems. The galvanized finish resists corrosion in humid or exposed install environments. The worm gear drive allows precise tightening to create a firm, low-leakage connection at duct joints. HVAC technicians and sheet metal installers use this clamp as a standard fastening component during ductwork installation and repair.

This clamp is suited for use on 6-inch semi-rigid or rigid aluminum flex duct and round duct collar connections. It is commonly installed in forced-air heating and cooling systems where aluminum duct transitions to a fitting, boot, or elbow. The 6-inch diameter matches standard residential trunk-to-branch and branch-to-register duct sizes. Installation is straightforward and does not require specialized tools beyond a standard screwdriver or nut driver.

Compatibility

Designed as an OEM-style replacement and standard-use clamp for 6-inch semi-rigid and rigid aluminum duct connections in residential and light commercial forced-air HVAC ductwork.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal installers. Power down the air handling unit and disconnect power at the disconnect or breaker before working on ductwork. Slide the clamp over the duct end before seating the duct onto the fitting, then tighten the worm gear screw with a flathead screwdriver or quarter-inch nut driver until snug. Do not overtighten to the point of deforming the aluminum duct wall.
