SAE AS33514 is an active aerospace standard that defines the dimensions and design requirements for a specific type of male fitting end used in flareless tube connections. Essentially, it provides the "recipe" for manufacturing fitting ends that can create a leak-proof seal without requiring the tube to be flared, often utilized in high-pressure hydraulic and pneumatic aircraft systems. Evolution and Context
Here is a short story about a high-stakes moment where this specific fitting made all the difference. The Ghost in the Line
Pitch diameter and other critical diameters must be concentric within strictly defined limits (e.g., within 0.008 F.I.M.). Squareness: 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.

Supplied sleeving must have a continuous operating temperature range of -55°C to +175°C, with short-term survivability up to 200°C.
standards to ensure proper sealing. Specific surfaces must be smooth and free from tool marks, though some annular marks may be allowed up to 100 microinches Ra. It includes specifications for different styles, such as Procurement and Military Use Fitting body – Corrosion-resistant steel (CRES, e
connections. Instead of widening the end of the tube, these fittings often use a "bite-type" sleeve or a gasket seal to create a leak-proof joint. saemobilus.sae.org Weight Savings:
