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. - Two stainless steel hose clamps help provide a tight seal on the 4 inch end and keep the reducer from falling out. 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. - 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. - 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.
