Simplify your dust collection setup with the HoseJoy magnetic hose connector system—a fast, frustration-free way to connect, disconnect, and reconfigure hoses across your entire shop.
This magnetic size down hose adapter allows you to quickly connect larger 4-inch dust collection hoses to smaller 2- to 3-inch hoses, pipes, or tool adapters without clamps, tabs, or hard-to-press buttons. Magnets on both sides pull the connection into perfect alignment, creating a secure, airtight seal that holds during use and releases easily with a small twist and pull.
Unlike traditional step-down adapters, this connector is fully magnetic on both ends and includes a lanyard hole, making it easy to tether to your dust extractor with paracord or elastic so it’s always within reach. It contains sixteen genuine N52 neodymium magnets, twice the magnets of single-sided adapters, providing exceptional holding strength without restricting airflow.
Designed for home workshops and professional shops alike, this adapter uses premium rubber O-rings to maintain suction and prevent leaks. The clamp-free, low-effort connection is especially helpful for users with arthritis or limited hand strength—no squeezing, threading, or wrestling with hoses.
This adapter is part of the HoseJoy system, a modular dust collection solution that lets you connect any size hose to any tool or extractor quickly and consistently. If you don’t see an adapter for your setup, message us—we’ll make one and add it to the system.
