This 200mm straight PVC joiner connects two lengths of round rigid duct in a continuous, aligned run. Its close-fitting profile supports a secure joint and maintains the smooth internal surface of the system, helping minimise leakage, pressure loss and regenerated noise when correctly sealed. Manufactured from lightweight, corrosion-resistant PVC, the fitting is easy to handle and install and is suitable for higher-volume residential and light-commercial supply or extract ductwork.
