Tank valve caps are an industry-standard piece of equipment, commonly used to protect the tank valve and o-ring from abuse, and also to differentiate between full and used tanks. Unfortunately, they are also a relatively flimsy item, prone to splitting or tearing and falling off of the tank. This can lead to divers incorrectly assuming a full tank has already been used and needlessly returning it to the fill station, or even worse having to retrieve a loose tank cap from the bottom of an exhibit.
Most aquariums have a ton of extra tubing or garden hose laying around, often too worn to be useful for anything but saved for some mystical future project. Proper gauge (usually 1 ¼”) sections of hose can be cut into small pieces and used to make a great in-house alternative to commercially available tank valve caps. These DIY valve caps are sustainable, virtually indestructible, and best of all free.
