#4 Male to 1/4in NPT 90 Deg Ano-Tuff Adapter

The #4 Male to 1/4in NPT 90 Deg Ano-Tuff Adapter by EARLS is a precision hydraulic and pneumatic fitting designed for systems requiring reliable 90-degree directional changes with mixed port configurations. This adapter serves operators, mechanics, and engineers who need to connect 4 AN male ports to 1/4 inch NPT male ports in tight spaces or angular mounting scenarios. The 90-degree geometry eliminates the need for separate elbows and reducers, streamlining assembly and reducing leak points in high-pressure fluid transfer applications.

Constructed from aluminum and finished with black anodized coating, this adapter combines lightweight durability with corrosion resistance essential for motorsport, industrial, and marine environments. The anodized finish (Ano-Tuff designation indicates enhanced hardness treatment) protects against salt spray, oxidation, and thermal cycling while maintaining excellent machinability and fitting concentricity. The 4 AN male connection accepts standard -4 hose or rigid tubing assemblies, while the 1/4 inch NPT male end threads directly into female NPT ports without additional adapters, ensuring proper fluid sealing and pressure integrity across mixed fitting standards.

This fitting is ideal for brake lines, fuel systems, coolant circuits, and air suspension setups where space constraints or system design require 90-degree transitions between AN and NPT thread types. Installation requires standard wrenches on both ends; the compact 2.9 x 0.7 x 3.45 inch profile fits into engine bays and frame rails without excessive vibration risk. EARLS fittings are trusted in racing, performance automotive, and industrial hydraulic markets for consistent performance under pressure and temperature extremes.
