AN To NPT 45 Degree -4 x 1/4in

The AN To NPT 45 Degree -4 x 1/4in adapter by ALLSTAR PERFORMANCE is a precision hydraulic and pneumatic fitting engineered for critical fluid transfer applications in high-performance systems. This adapter bridges AN (Army-Navy) and NPT (National Pipe Taper) thread standards—a conversion essential in custom fluid systems, motorsports fuel injection setups, and tactical equipment where space constraints and directional flow control demand angled configurations. Whether you're building a race-proven fuel system or retrofitting military-grade hydraulic assemblies, this fitting ensures reliable, leak-free connections where 90-degree orientation isn't feasible.

The 45-degree geometry optimizes fluid dynamics in confined spaces while the -4 AN size (1/4-inch NPT male thread) delivers consistent pressure ratings across standard mil-spec and commercial hydraulic circuits. ALLSTAR PERFORMANCE's manufacturing maintains tight tolerances on thread engagement and seal interfaces, preventing micro-leakage in high-vibration environments common to vehicles and field-deployed systems. The compact 2.45-inch length and 0.7-inch diameter profile allow integration into dense manifold assemblies without requiring major rework of existing plumbing—a critical advantage when upgrading legacy equipment or finalizing prototype designs.

This adapter is ideal for fabricators, motorsports technicians, and field engineers who routinely work with mixed-standard fittings in fuel systems, brake circuits, or compressed-air applications. Installation requires only standard wrench sizes and Teflon tape on the NPT threads; the angled configuration eliminates the need for separate 90-degree elbows, reducing overall assembly weight and clutter. Verify NPT thread compatibility with your host manifold before ordering to ensure seamless integration into your tactical or high-performance system.
