Sae-as33514 (2025)

: The baseline adoption by SAE International.

AS33514 continues to be the valid standard for maintenance, repair, and overhaul (MRO) of systems that were originally designed with it.

: Unlike flared fittings that require the tube end to be widened, flareless fittings use a sleeve or ferrule that bites into the outer diameter of the tube, creating a mechanical seal. sae-as33514

The current list price for SAE AS33514E is $105.00 USD. Prices may vary slightly by distributor.

| 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 | : The baseline adoption by SAE International

In an industry where we are losing senior mechanics to retirement and asking junior technicians to do more with less, we need hardware that is mistake-proof . AS33514 delivers that.

), though some versions were marked inactive for new designs as of 2008. Associated Hardware MIL-DTL-27272 Revision D Amendment 2 - DLA The current list price for SAE AS33514E is $105

: Which bites into the tube to create the seal.

: AS33514 fitting ends are designed to be compatible with other standard components, such as those defined in SAE-AS4395 or SAE-AS18280 .

By rigorously defining the , SAE AS33514 ensures that components from different manufacturers can be confidently assembled into a safe, reliable, and leak-proof system. As the aerospace industry evolves, standards like AS33514 will remain the foundation of interoperability, safety, and quality.
