One of the reasons that this fitting is used so often within the woodworking industry, is that many of us don’t want or need a large dust collection system in our garage or workshop. With this fitting, you’ll be able to reduce your hose size down to the 2 1/2 inch size which the most commonly used size for most big box store wet/dry vacuums and shop vacuums.
This cone shaped reducer can be also be used on machinery with a little help from some other accessories. Typically the reducer works with hose since it is basically the same size as your 4 inch and 2 1/2 inch machinery or shop wet/dry vac ports. With a 4 inch diameter rubber coupler (sold separately) or a short section of 4 inch hose you can connect the reducer directly to a 4 inch port on machines like band saws, table saws, large planers and more.
Most wet/dry vacuum hoses will plug directly into the smaller end of this fitting making it a super value for most of us weekend warrior type woodworkers. There are some vacuum units that use different size hoses and hose adaptors so please be sure to measure your hose and machine ports before making a purchasing decision.
Made from high quality ABS plastic for extended periods of use, this fitting will withstand the constant friction and debris flow of woodworking dust collectors. The reducer measures: Nominal 4 inch end is 3-61/64” OD and 3-41/64” ID; 2-1/2” nominal OD end measures 2-15/32” OD and 2-9/32” ID. All of the dimensions may slightly vary due to slight variations in the manufacturing process.
