This straight connector joins two lengths of 220 x 90mm flat PVC duct to form a continuous, aligned air path. The close-fitting profile supports a mechanically secure connection and helps maintain the smooth internal surface of the duct system, reducing unnecessary turbulence and pressure loss. Manufactured from lightweight, corrosion-resistant PVC, the connector is easy to fit and seal on site. It is suitable for residential and light-commercial supply or extract systems installed behind cabinetry, within ceiling voids or through other space-constrained areas.
