CPAP OXY Nozzle

If you buy the wrong hose for your CPAP like I did and need the nozzle for your oxygen machine. Drill a 1/4"(6.5mm) hole into the flat side of your hose fitting (the left arm of the T of where it connects to your machine). bezel outside with a small knife. Place nozzle on index finger and maneuvering nozzle through the hose fitting drop it into the hole and push until nozzle base is flush with the back of the hose fitting wall.
