AN To NPT Straight -4 x 1/8in

The AN To NPT Straight -4 x 1/8in adapter from Allstar Performance provides a reliable transition between different plumbing standards for fluid transfer systems. This specific fitting features a -4 AN male end and a 1/8-inch NPT male end, allowing users to connect braided hoses or specialized equipment lines to standard National Pipe Thread ports commonly found on manifolds, fuel blocks, and pressure sensors. By bridging these two distinct thread types, this adapter simplifies complex plumbing tasks in high-performance and tactical support environments.

Constructed from lightweight yet durable aluminum, this adapter is designed to withstand the rigors of high-pressure applications without adding unnecessary weight to the assembly. The black anodized finish serves a dual purpose, offering a professional aesthetic while providing essential protection against corrosion and wear in harsh conditions. When you buy this fitting, you are investing in a component engineered with precise tolerances to prevent leaks and ensure a secure mechanical connection that remains stable over time.

This straight adapter is a critical component for those performing custom plumbing work or maintaining specialized machinery. The 1/8-inch NPT side is standard for many gauge senders and vacuum ports, while the -4 AN side utilizes a 37-degree flare seat to create a metal-to-metal seal that remains effective even under significant vibration. Reviewing the specifications of your existing hardware is vital to ensuring compatibility, and this Allstar Performance fitting offers the consistency required for professional-grade installations where failure is not an option.

Whether you are managing fuel delivery, oil circulation, or pneumatic control systems, the ALL49505 ensures a streamlined flow path with minimal restriction. The compact design allows for installation in tight spaces where larger fittings might interfere with surrounding components. For those seeking reliable specifications and proven performance in fluid management, this adapter represents a standard-setting solution for connecting AN-style lines to NPT-threaded ports with complete confidence.
