This fitting allows you to quickly connect a 102mm hose to the larger 100mm dust ports common on power tools such as planers and table saws. One end accepts industry standard 102mm OD hose and the opposite end has a 100mm rubber cuff and a steel hose clamp that can be securely attached to the 100mm dust collection port of the power tool. The rubber cuff can easily be loosened and switched between machines when using just one dust hose. This hose fitting is made from a thermoplastic polymer, which is impact resistant, has structural strength and stiffness and will not flex or distort under pressure. It has excellent low temperature properties and will perform in extremely cold workshops down to -40°C. As all of our fittings are made to exacting and tight tolerances to prevent air loss, a top tip is to use a washing up liquid as a lubricant when initially installing. ©
