#4 Stl Flare to 1/8in NP Adapter

The #4 Stl Flare to 1/8in NP Adapter is a precision straight-thread fitting designed to bridge incompatible hydraulic and pneumatic line connections in fluid transfer systems. This adapter allows technicians and equipment operators to mate a 4 AN male flare port with a 1/8 inch NPT male port, eliminating the need for costly line replacements or custom fabrication. Common applications include aircraft maintenance, heavy equipment servicing, industrial machinery, and mobile hydraulic systems where adapter fittings standardize disparate port configurations.

Manufactured by AEROQUIP under part number FBM2512, this adapter features a steel body with zinc oxide plating to resist corrosion and extend service life in demanding environments. The straight-thread design ensures reliable sealing without bend stress, while the robust construction handles pressure cycling and vibration typical of mobile and industrial applications. Zinc oxide plating protects the steel substrate from rust and oxidation, maintaining integrity whether the adapter operates in shop conditions or harsh field deployments. The compact footprint—measuring 2.95 inches in length and weighing just 0.05 pounds—allows installation in tight spaces without adding bulk to system assemblies.

Technicians in aerospace, automotive, and agricultural sectors rely on AEROQUIP adapters to maintain fleet equipment and repair machinery on schedule. The 4 AN to 1/8 inch NPT configuration addresses situations where original OEM fittings have become unavailable or where equipment upgrades require cross-compatibility between legacy and modern hydraulic standards. Installation requires hand tools only—no special equipment needed—making this adapter ideal for field service calls and workshop maintenance.
