Thread: How can I connect a tube to a regular plastic bottle?

I want to connect some aquarium tubing to a regular plastic bottle, somewhere on the side, low down. It has to be a water and air tight connection and the bottle will contain water that will be drank so if any apoxies are used they have to be safe.

How would you do it?

Go to the hardware store, get a brass reducing bushing, one that your hose will fit into, get some o-rings, and a flare fitting, one that your hose will fit in, and try this.

Push your hose up through the plastic bottle put the brass reducing bushing on it then pull it through the hole in the bottle, put the ring inside the bottle between the reducing bushing and the bottle, then screw your flare fitting on the bushing, and it should hold and be water tight.

I would not drill through the side of the bottle. Instead use the cap and drill a hole in the cap and insert the tube through the hole. If your need an air tight connection and expoxy isn't an option then you need to use a bulkhead fitting ang gasket.
