Ducted vacuum 90 degree short elbow. Only use this elbow right at the back of the inlet valve or next to the power unit. For anywhere else along the pipework, use long radius 90 degree sweep elbow instead to avoid blockages.
Suitable for use with ducted vacuum PVC pipes that measure 50mm in diameter on the outside.
Please note that ducted vacuum systems have their own standard pipe and fittings, this fitting is NOT the same as the one used in water plumbing.
