When a need exists to extend the reach of a shop vacuum this 13 foot wet dry vacuum hose is perfect. The 2-1/2-inch diameter provides a larger opening for debris collection and maximum airflow. This wet dry vacuum hose features DUAL-FLEX® technology that resists crimping and collapsing, and adds 180-degree flexibility at both shop vacuum hose ends. The locking tab won't pull loose during use, but easily attaches unlike many shop vacuum hoses. This wet dry shop vac hose works with 2-1/2-inch shop vacuum accessories, and fits most shop vacuums with the standard 2-1/2-inch inlet port opening including most WORKSHOP Wet/ Dry Vacs.
