In the high-stakes world of aerospace engineering, is more than just a technical code—it’s the silent guardian of a plane’s "circulatory system." This Aerospace Standard defines the precise dimensions for flareless tube connection fitting ends, ensuring that hydraulic lines can withstand immense pressure without leaking.
Specifically, SAE-AS33514 defines the design, performance, and testing requirements for . While the title might sound esoteric, the standard governs the tiny but mighty connectors that hold thousands of pounds of hydraulic pressure inside aircraft landing gear, flight control actuators, and braking systems. sae-as33514
In simple terms, SAE-AS33514 specifies how to make a leak-proof, vibration-resistant fitting without using a traditional flare. This "flareless" design is a game-changer for durability and maintenance. SAE AS33514 In the high-stakes world of aerospace
: Surface roughness must comply with ANSI/ASME B46.1 to prevent leaks at the sealing interface. Boeing 737, 777, 787 Airbus A320, A350 Lockheed
| Feature | AS33514 | AS8642 (Diluter-Demand Regulator) | |--------|---------|-------------------------------------| | Flow type | Continuous | On-demand + dilution | | Outlet pressure | 50 psig | 0–600 psig (variable) | | Gauges | Integral | Separate or cockpit remote | | Altitude range | ≤25,000 ft | ≤50,000 ft | | Complexity | Low | High | | Oxygen efficiency | Poor | Excellent |
Failure in any of these tests disqualifies a product from claiming compliance with SAE-AS33514.
