- Designed for screw locking CO2 connections to prevent pipe loosening under pressure, reducing the risk of leaks and damage. - Features super micro hole atomization, a U type air intake pump, and an invisible check valve for improved atomization performance and safety. - High quality construction and reliability for demanding CO2 applications. - Material: not specified. Size options: approx. 6.5 x 4 x 2.5 cm (2.56 x 1.57 x 0.98 inches) or approx. 7 x 5 x 3.5 cm (2.76 x 1.97 x 1.38 inches). - Use scenarios: - Connects CO2 lines in beverage dispensing or carbonation setups to maintain a secure, leak-free connection under pressure. - Suitable for small scale spraying or humidification tasks that require fine atomization and a backflow-preventing check valve. - Useful in DIY pneumatic projects where a compact CO2 locking and atomization module is needed.
