AN To NPT Straight -4 x 3/8in

The AN To NPT Straight -4 x 3/8in fitting from ALLSTAR PERFORMANCE is a critical hydraulic and pneumatic adapter used across military, law enforcement, and industrial equipment platforms. This straight connector bridges AN (Army Navy) and NPT (National Pipe Thread) standards, enabling seamless integration between incompatible port configurations on tactical vehicles, weapons systems, and fluid-transfer assemblies. Whether you're maintaining field equipment, building custom hydraulic rigs, or servicing legacy military hardware, this adapter eliminates costly workarounds and downtime.

Engineered to military-grade standards, the AN To NPT Straight fitting delivers reliable performance in high-pressure environments. The -4 size (1/4" AN) connects to 3/8" NPT ports, providing a direct thread interface without adapters or reducers that create weak points or leaks. Precision-machined construction ensures zero thread wobble and consistent seal integrity under operational pressures found in tactical platforms, pneumatic brake systems, and hydraulic distribution networks. The compact 2 x 1.1 x 4.05-inch profile allows installation in space-constrained mounting locations common on armored vehicles and crew-served weapon systems.

Field technicians, armourers, and maintenance personnel rely on this fitting for rapid system repairs and custom equipment builds. Installation is straightforward—apply thread sealant to the NPT end, hand-tighten, then use a wrench to secure to specification. Compatible with any platform using AN -4 and 3/8" NPT ports, including hydraulic suspension systems, air-brake assemblies, and fluid circulation circuits. The lightweight 0.05-pound design ensures minimal impact on vehicle weight and balance. Keep this adapter in your tactical maintenance kit for emergency field repairs and non-standard port conversions.
