4″ Right-Threaded Flex Hose Adapter | Male

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.

Sized for common 4″ right-threaded flex hose, where the threads of the hose are angled up and to the right, this male 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.

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 right-threaded 4″ flex hose.

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.
