✔️ 4 Inch OD flexible TPU plug stops dust leak shop vac systems

These heavy duty pipe plugs seal open ports to stop airborne debris from backing up your dust extraction system and clogging active tools. You can push these snap on covers onto standard 4 inch round tubing to create an airtight vacuum seal during idle time, keeping pressure stable and saving cleanup time across busy garages and job sites.

✅ Dual seal ring design clamps firmly to hold steady suction and lock loose sawdust away.
✅ TPU flexible material grips round tubes evenly without needing clamps or hot glue.
✅ Anti slip textured skin resists scuffs and stays flex through wet shops and dry jobs.
✅ Multi purpose protective caps swap out fast when you need to reroute hoses between stations.
