204x60mm Self-Seal Coupling For Plastic Duct to Duct Join

This Self Seal Coupling System eliminates the need for sealant or tape by ensuring that air leakage in or out of the duct joints is kept to an absolute minimum. The unique design provides consistent joint quality & joint integrity and couples with conventional ducting. Once together the systems form an almost air tight installation. This significantly reduces installation time and can be removed and re-made for alteration, maintenance and cleaning.
