Parker 44004-04A-N1 Quick-Disconnect Fitting for Ground Support Equipment - Hydraulic Fluid (Red Oil

The Parker 44004-04A-N1 Quick-Disconnect Fitting is a thread-together style self-sealing coupling designed specifically for connecting ground support carts to aircraft hydraulic systems. This coupling offers reliable performance, simple one-handed operation, and positive latching to ensure secure, leak-free connections during aircraft ground maintenance. With its durable aluminum alloy anodized body, it is engineered for long-term reliability, making it an essential component in both commercial and military programs.

Key Features

• High Pressure Rating: The coupling supports a maximum operating pressure of 3000 psig and burst pressure of 7500 psig, ensuring reliable performance in hydraulic systems.
• Fluid Compatibility: Designed for use with hydraulic fluids such as Red Oil (5606/83282), making it ideal for aircraft ground support systems.
• Efficient Fluid Flow: The self-sealing valve minimizes pressure loss and turbulence while allowing fluid flow, and its flush-faced design reduces air inclusion or spillage during coupling or uncoupling.
• Positive Latching Mechanism: Features a ratchet-tooth style latching system that ensures the coupling halves are positively locked in place for added safety and security.
• Durable Construction: Constructed from anodized aluminum alloy for corrosion resistance and long-lasting performance, even in harsh environments.
• Compact Design: With a 1/4 inch inlet and 3.15-inch overall length, this coupling is perfect for installations with limited space, offering reliable, high-performance operation.
