Dundas Jafine FDC4 4 Inch Duct Connector Kit

Product Description

The DUNDAS JAFINE FDC4 is a 4-inch duct connector kit designed to join two sections of flexible duct or rigid aluminum pipe in a single, secure connection. The kit includes one aluminum duct connector crimped on one end and smooth on the other, along with two adjustable plastic clamps. Licensed HVAC technicians and installers use this fitting when extending or repairing ductwork in tight residential applications. It also serves as a dryer exhaust extension, making it a dual-purpose component for both HVAC and laundry ventilation work.

This connector is suited for residential installations where flexible aluminum foil duct, vinyl duct, or aluminum pipe sections need to be joined without specialized tooling. It is a practical solution for dryer vent extensions and general forced-air duct connections. The crimped end slides inside adjacent duct sections to reduce turbulence at the joint, while the smooth end accepts duct sleeved over it. HVAC and appliance installation technicians working on dryer exhaust systems or supply and return ductwork will find it straightforward to deploy.

Installation Notes

Installation is performed by HVAC technicians or qualified appliance installers. Disconnect power to any connected appliance and ensure the dryer or air handler is off before beginning duct work. Slide the crimped end into the upstream duct section and the smooth end into or over the downstream section, then tighten both clamps evenly. Follow applicable local mechanical codes and manufacturer duct-length guidelines when extending dryer exhaust runs.
