Welding Gas Quick Couplings – AE Series
The AE welding quick couplings from the POOLKE AE Series are designed for oxygen and fuel-gas connections used in welding, cutting and gas distribution equipment. The series combines quick one-hand operation with dedicated configurations for different gas circuits, helping operators connect hoses and regulators efficiently while maintaining clear separation between oxygen and flammable-gas lines.
The AE Series uses chrome-plated steel components and provides male thread, female thread and hose barb connection options for different welding-system layouts. Fuel-gas socket sleeves are marked in red for easier identification, while selected plug versions include an integrated back-flow stop valve for additional protection against reverse gas flow. The catalog also specifies oil-free material requirements for improved safety in gas-service applications. With multiple thread and hose sizes available, the AE welding quick couplings provide a flexible connection solution for fabrication shops, welding stations and industrial gas equipment where safe identification and dependable operation are essential.
