Fulton 4 inch to 2 1/2 inch Reducer Fitting for Dust Collection Hose to Hose Connections and 4 Inch Port Connections on Larger Machinery

#ad
Fulton #ad - 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. All of the dimensions may slightly vary due to slight variations in the manufacturing process. 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.

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. 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. 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. 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.

With a couple of hose clamps not included this reducer does its job perfectly and more! 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. The fulton 4 inch to 2 1/2 inch reducer has been designed with a specific purpose in mind. 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. That purpose is to connect the industry standard 4 inch diameter dust collection hose with the other industry standard 2 1/2 inch diameter dust collection hose.
