The Waste Coupler, Straight, 4-Inch (GA) is a ground support component used in aircraft lavatory servicing systems. Designed for general aviation (GA) aircraft, this straight coupler connects waste hoses to the aircraft waste port, enabling safe and efficient removal of lavatory waste during servicing operations.

Constructed from durable, chemical-resistant materials, the coupler ensures a secure, leak-resistant connection while withstanding exposure to waste fluids and cleaning agents. Its 4-inch standard size is compatible with many general aviation lavatory service configurations.

Its primary functions include:

Providing a secure connection between waste hose and aircraft service port
Ensuring hygienic and controlled transfer of lavatory waste
Supporting efficient ground servicing operations for GA aircraft

Waste couplers like this are essential tools in airport ground handling, helping maintain sanitation standards and streamline aircraft turnaround procedures.
