Description
This duct coupling is designed to join two duct fittings such as 90 / 45-degree bends or reducers together. This will slip inside and form a firm and fast seal minimising installation time and allowing you to easily assemble and disassemble your duct run for maintenance or to experiment with different ductwork system designs. This item is designed for use with safe seal galvanised metal ducting but it can be used with equivalent standard metal ducting or some plastic ducting ranges. It is perfect as part of a longer duct run such as for hydroponics in-line ventilation systems air conditioning heat recovery systems or positive pressure/input ventilation systems.
