#4 > 1/8 Npt 45

The EARLS #4 to 1/8 NPT 45-Degree Adapter Fitting is a precision-engineered hydraulic and pneumatic line connector designed to transition 4 AN male ports to 1/8-inch NPT male threads at a 45-degree angle. This fitting is ideal for applications where space constraints or routing requirements necessitate an angled connection, making it essential for compact engine bay layouts, fuel system installations, and transmission cooler line work.

Constructed from zinc-plated steel, this adapter resists corrosion across automotive, aerospace, and marine environments. The 45-degree configuration reduces the footprint of plumbing layouts compared to straight adapters, allowing for smoother routing of lines without sharp bends that could compromise flow or create stress points in hoses and hard lines.

This adapter is specified for custom fuel systems, supercharger installations, nitrous oxide systems, oil cooler setups, and transmission line plumbing where AN-to-NPT conversion is required. With a weight of just 0.04 lbs and compact dimensions (0.95 x 0.6 x 3.05 inches), it adds minimal weight while delivering the necessary thread conversion for mixed-standard hydraulic and pneumatic circuits.
