These clamps fit neatly into the slots around the coupler so there is no slipping when tightened. No more busting your knuckles. Each clamp is equipped with a blue turn key mechanism to make tightening and loosening the clamp super easy.

Works with Most Wet/Dry Vacuum Hoses

Most wet/dry vacuum hoses will plug directly into the smaller end of this fitting making it a super value for most professional and 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.

The Perfect Kit for a 4" Port

Most common workshop machines are equipped with a 4" port. This kit is perfect for those who don't own a large dust collector or simply want to use a shop vacuum for certain projects

High Quality Durability

Made from high quality ABS plastic for extended periods of use, the reducer fitting will withstand the constant friction and debris flow of woodworking dust collectors. The reducer measures: Nominal 4” 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. Dimensions may slightly vary due to slight variations in the manufacturing process.

Easy to Install and Easy to Remove

The rigid rubber coupler seals tightly around the reducer for excellent airflow. Easy to install and easy to remove. As with most all other dust collection fittings, it’s always a good idea to have extra on hand for when you need it. It’s always better to have it and not need it than it is to need it and not have it. The coupler measures: 4-5/16" OD and 4” ID. Height: 2-3/4"
