16AN to 16AN 1in NPT Straight Male to Male

The 16AN to 16AN 1in NPT Straight Male to Male fitting from REDHORSE PERFORMANCE is an essential component for high-flow fuel, oil, and coolant systems in performance automotive applications. This adapter bridges two 16AN hose connections while incorporating a 1-inch NPT male thread port, making it ideal for builders integrating aftermarket fuel rails, turbo feed lines, or custom cooling circuits into their engine bay.

Constructed from precision-engineered aluminum and featuring a straight body design, the 16AN to 16AN 1in NPT fitting maintains full flow capacity without unnecessary pressure drops—critical when running high-volume fuel pumps or tight turbo cooling loops where every PSI matters. The dual 16AN male ports accept standard -16 hose ends and swaged connections, while the 1-inch NPT male port accepts gauge adapters, pressure switches, or additional feed/return lines without requiring multiple fittings.

Mechanics and engine builders working on fuel system upgrades, turbocharger installations, or custom plumbing will find this fitting provides the versatility needed for non-standard layouts where direct AN-to-AN connections won't solve their plumbing challenges. REDHORSE Performance's manufacturing tolerances ensure leak-free sealing when paired with proper AN-spec hose and fittings, eliminating the guesswork that plagues budget alternatives.
