4AN Quick Disconnect Dry-Break Fitting, -4 AN with -5 body, Anodized Aluminum, for Fuel & Oil use

This -4 AN anodized aluminum quick disconnect dry-break is perfect for use in cooling, fuel, or oil lines where ease of maintenance is a priority:

• Quick-Disconnect: Both male and female ends are clean dry-breaks. Prevents liquid in the line from coming out when disconnected.
• 7/16″-20 male AN4 threads on either side.
• O-ring seals are Fluorocarbon, often known by the trade name Viton™ for use with oils, mineral greases, nitrogen, and fuels. Fluorocarbon is a high-performance elastomer prized for outstanding resistance to extreme heat (up to 400°F/200°C+), aggressive chemicals, fuels, oils, and weathering, making it ideal for automotive, aerospace, and industrial uses where standard rubber fails.
• 7/32″ flow diameter.
• Cross section (in²): 0.037.
• Max psi: 3,250.
• Body length not including threads is 1.94″ or 49.2mm.
• Knurled handle on the female side for easy grip.
• Comes with -4 AN plastic caps to protect threads.
• Part # QDSPH0504AL-F.

This -4 AN quick disconnect shares its -5 disconnect body with our -6 AN version (QDSPH0506AL-F) — same dry-break body, different thread ends, so you can standardize on one disconnect style across multiple line sizes in a build.

Beyond motorsport fuel and oil systems, this Viton-sealed dry-break is well suited to fuel, oil, and hydraulic quick-disconnects in experimental aircraft, drones, robotics, and marine fuel systems where fast, clean line separation is needed for maintenance or field service.
