Endura Adapter Fitting #8 to 3/8 NPT Straight

The Endura Adapter Fitting #8 to 3/8 NPT Straight is a precision hydraulic and pneumatic adapter designed for professionals who demand reliable fluid transfer connections in high-pressure systems. This straight adapter bridges two industry-standard port types—AN-8 (Aircraft Standard) and NPT (National Pipe Thread)—making it essential for custom fluid system installations, automotive racing platforms, industrial machinery, and tactical equipment builds. Whether you're configuring a custom cooling loop, integrating hydraulic actuators, or assembling fuel delivery systems, this adapter provides the critical link between incompatible thread standards.

Constructed from aerospace-grade aluminum and finished with nickel anodization, the Endura adapter combines lightweight durability with corrosion resistance—critical for systems exposed to moisture, salt environments, or temperature cycling. The nickel-anodized surface protects against oxidation while maintaining low weight at just 0.07 lbs, making it ideal for weight-sensitive applications like motorsports and mobile tactical systems. The straight configuration eliminates flow turbulence common in 90-degree elbows, reducing pressure drop and improving system efficiency. Male-to-male threading on both ends ensures secure, leak-free connections when paired with compatible female couplers or manifold ports.

This adapter fits seamlessly into systems requiring conversion between AN fittings (common in performance automotive, aerospace, and military applications) and NPT ports (standard in industrial hydraulics and pneumatics). Installation requires compatible female 3/8" NPT and AN-8 couplers; ensure proper thread sealant or PTFE tape is applied to NPT sides to prevent leakage. The compact 5.3-inch length suits tight engine bays and equipment enclosures. Ideal for engineers, mechanics, and equipment specialists sourcing reliable adapters for custom fluid system builds where code compliance and pressure integrity are non-negotiable.
