The GCC Series is a specially designed gas charging coupling system developed for refrigerant filling, vacuum testing, and performance evaluation of air-conditioning and sealed gas systems.
Engineered for speed, safety, and precision, these couplings allow secure connection and disconnection under pressure, ensuring reliable sealing throughout testing and production cycles.
Its lever-actuated locking design provides firm engagement with minimal effort, allowing technicians to operate the system quickly and safely. An integrated automatic shutoff valve instantly seals the flow path during disconnection to prevent gas escape, while the fail-safe mechanism keeps the valve closed even if the lever is operated without a plug — completely eliminating the risk of accidental gas release.
Built from nickel-plated brass or stainless steel, the GCC Series is robust, corrosion-resistant, and suitable for continuous use in refrigerant and vacuum lines. Designed for high-cycle reliability, it maintains consistent sealing performance over extended operation.
Available in 1/4” and 3/8” sizes, it connects seamlessly with standard AC charging ports, making it the go-to choice for HVAC and air conditioner OEMs.
