silicone purge valve?
what is a silicone purge valve.
A purge valve is used when a system or object can sometimes be filled with unwanted substances during normal use, as a way to eliminate those substances without complete disassembly. A 'spit valve' (a kind of purge valve) is built into some musical instruments to allow getting rid of saliva which builds up inside during playing. Snorkels used for skindiving often have purge valves (some even made from silicone) to make clearing water easier. A purge valve may be used to drain occasional condensation from inside a gas line.
