Product Description
The 53b423-004 is a 3/8-inch 90-degree short fitting designed for aircraft vacuum and pressure pump plumbing systems. This high-flow connector interfaces with 5/8-inch hoses on Sigma-Tek rotary-vane pump installations, routing air lines through confined engine compartment spaces. The compact 90-degree elbow minimizes airflow restriction while maintaining directional changes in pump inlet and outlet circuits.
Install per Sigma-Tek pump manufacturer specifications and applicable aircraft maintenance documentation.
