1/4″ Anti-Vacuum Valve

There are many names for this part, but a brief description should suffice: this valve allows air to escape the boiler as the water heats up, hissing and then closing off when the boiler water reaches its operating temperature, sealed by the steam pressure created. This is interchangeable with the other version as well . A gasket is recommended for this version, however.
