These dust hose rubber cuff connectors are essential for joining fittings of the same 63mm outside diameter, used for connecting ducting, blast gates, bends, T connectors, machine dust ports and more.Each connector is constructed from a strong, heavy duty rubber, whilst allowing for a degree of flexibility to either add a slight curve to fixed ducting or to adapt to narrow variations in fitting size and alignment.Once fitted, the cuff connectors are secured tightly in place using the two jubilee hose clamps, each nestling within moulded grooves around the perimeter. Measuring 65mm in length, each connector provides substantial depth and surface contact with fittings to guarantee a stable, non-slip fit. The 63mm smooth internal bore ensures optimum air flow is maintained to allow the smooth passage of dust. ©
