This magnetic 4 inch flex hose adapter is part of the HoseJoy magnetic hose connector system, providing a fast, frustration-free way to connect 4″ flex hose to dust collectors or other hoses without clamps, tabs, or hard-to-press fittings.

Sized for common 4″ flex hose, including Powertec hose available from Home Depot and Amazon, this male adapter is designed to point toward the vacuum source in the HoseJoy system. The female end always points toward the tool, creating consistent airflow direction and repeatable connections across your dust collection setup.

Powerful N52 neodymium magnets pull the connection into place, while premium rubber O-rings create a secure, airtight seal that preserves airflow and suction. A small 1/16-turn twist and gentle tug releases the magnets, making hose changes quick and low-effort—especially helpful for users with arthritis or limited hand strength.

This magnetic 4 inch flex hose adapter can be used with or without a hose clamp and will fit most left-threaded 4″ flex hose, which accounts for the vast majority of hoses on the market. It’s designed for both home workshops and professional shops where durability and speed matter.

Part of the HoseJoy system, this adapter works with our tool adapters, vacuum port adapters, blast gates, and other hose end adapters (sold separately). If you don’t see the exact adapter you need, message us—we’ll make it and add it to the system.
