#3 Stl Flare to 1/8in NP Adapter

The AEROQUIP #3 Steel Flare to 1/8in NPT Adapter (FBM2511) is a straight-thread adapter fitting engineered for hydraulic and pneumatic systems requiring reliable conversion between AN male and NPT male ports. This adapter connects 3 AN male fittings to 1/8 inch NPT male ports, making it essential for fluid power applications where different threading standards must be joined without compromise or leakage.

Constructed from steel with a zinc oxide finish, the adapter delivers corrosion resistance suitable for industrial and mobile equipment environments. The straight-thread design eliminates the complexity of swivel fittings while maintaining a compact footprint—weighing just 0.04 lbs and measuring 2.8 x 0.55 x 5.95 inches. AEROQUIP's manufacturing standards ensure precise thread tolerances and a secure seal when properly installed with compatible sealants or tape on NPT threads.

This adapter serves technicians and engineers working with hydraulic power units, pneumatic control systems, mobile equipment, and stationary fluid power circuits. It solves the common integration problem when system components arrive with mixed thread standards—3 AN on one side (AN flare fittings) and 1/8 inch NPT on the other (pipe-threaded ports). The zinc oxide coating provides baseline corrosion protection for indoor and light outdoor use; for harsh saltwater or high-vibration environments, additional preventative measures may be warranted.

AN (Army-Navy) flare fittings and NPT (National Pipe Thread) represent two foundational hydraulic connection standards in North American industry. AN fittings use a 37-degree flare seal and are common in aircraft, automotive, and precision hydraulic assemblies. NPT connections rely on tapered threads and are standard in plumbing and general industrial applications. Choosing the correct adapter ensures system integrity and eliminates retrofitting delays.
