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 tools without clamps, tabs, or hard-to-press fittings. This version has doubled magnets for extra hold in some extreme conditions.
*NOTE: please call or email first before ordering this adapter, because in most cases it’s unnecessary and the normal U4-002 is what you need.*
Sized for common 4″ flex hose, including Powertec hose available from Home Depot and Amazon, this female adapter is designed to point toward the tool in the HoseJoy system. The male end always points toward the vacuum source, while the female end creates a consistent, repeatable connection at the tool side of your dust collection setup.

The male end always points toward the vacuum source, while the female end creates a consistent, repeatable connection at the tool side of 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 built for both home workshops and professional shops where durability and ease of use 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.

HoseJoy is a system created with the goal of standardizing the connectors between every dust collection machine, every hose, and every tool. If we don’t currently have what you’re looking for, we’ll make you a custom connector and add it to our catalog.
Designed for home workshops and pro shops alike, these connectors use powerful N52 neodymium magnets and premium rubber O-rings to create a secure, airtight fit between dust extractors, hoses and tools. No clamps, no struggling—just click, connect, and get back to work. A small 1/16th turn and tug in either direction releases the magnets allowing you to quickly detach your hose from one tool and effortlessly attach it to another. Perfect for folks who have arthritis and who want to save time and avoid frustration.
