Aircraft Hydraulic Fittings by AN, MS, NAS, and AS Reference

Aircraft hydraulic fitting searches often begin with a standard number. This directory organizes references such as MS21922 / AS21922, AN941, AN826 / MS20826, AN916, AN838 alongside manufacturer and description data. Preserve the complete designation because dash numbers and suffixes may define characteristics.

Reading a Hydraulic Fitting Designation

AN, MS, NAS, and AS identifiers belong to different standard families. A superseding reference should be confirmed against the specification revision; similar dimensions or catalog cross-references do not establish interchangeability.

Depending on the standard, a designation may indicate fitting style, size, thread, material, finish, shape, and end configuration.

Fitting Forms and Connection Functions

Aircraft hydraulic fittings may include:

• Straight unions, elbows, tees, and crosses
• Bulkhead fittings and mounting adapters
• Reducers, expanders, nipples, and bushings
• Flared or flareless tube fittings
• Hose fittings, couplings, and swivels
• Caps, plugs, sleeves, nuts, and hardware

These forms allow hydraulic lines to change direction, branch, terminate, pass through structure, or connect components. Material and pressure capability must match system requirements.

Where Hydraulic Fittings Are Used

Fittings may appear in flight-control, landing-gear, brake, steering, actuator, and fluid-power installations. Wheel and braking requirements may involve the aircraft brake parts catalog.

System association alone does not establish aircraft applicability.

Confirm the Fitting Configuration

Before selecting a record, verify:

• Part number and specification revision
• Tube, hose, and thread sizes
• Material, finish, and pressure rating
• Angle, end style, and installation position
• Aircraft model and serial-number effectivity
• Manufacturer, NSN, or CAGE Code when assigned
• Condition, certification, and traceability requirements

Compare these details with the illustrated parts catalog, maintenance manual, specification, drawing, and engineering data. The aircraft components directory covers system parts beyond hydraulic fittings.

Request Pricing for a Hydraulic Fitting

Submit the designation, manufacturer, quantity, condition, aircraft application, required date, destination, and documentation needs. ASAP Semiconductor can review sourcing options, pricing, availability, lead time, and records. Catalog presence does not confirm compatibility or installation eligibility.
