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 designed for critical fluid transfer applications in high-performance systems. This adapter bridges AN (Army-Navy) and NPT (National Pipe Taper) thread standards, making it essential for custom fluid systems, motorsports fuel injection setups, and tactical equipment where space constraints and directional flow control require angled configurations.

The 45-degree geometry of this fitting optimizes fluid dynamics in confined spaces, while the -4 AN size corresponds to a 1/4-inch NPT male thread, ensuring reliable, leak-free connections. 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.

This adapter is ideal for fabricators, motorsports technicians, and field engineers who routinely work with mixed-standard fittings in fuel systems, brake circuits, or hydraulic assemblies. Its compact design allows for easy integration into dense manifold assemblies without requiring significant rework of existing plumbing, making it a critical advantage when upgrading legacy equipment or finalizing prototype designs.
