Engineered for high-pressure pneumatic engine starting, this premium straight coupler provides a secure, leak-free connection between the Air Start Unit (ASU) hose and the aircraft ground start receptacle. It safely handles high-temperature, high-velocity airflow without pressure loss. Machined from lightweight anodized aluminum to reduce crew fatigue, it is equipped with heavy-duty protective guard rings to shield the assembly from impact drops and tarmac abrasion.
