Reducer AN Male -12 to -16

The Reducer AN Male -12 to -16 from Allstar Performance is a crucial adapter fitting designed for high-performance fuel and coolant systems that require stepped hose connections. This reducer transitions from a larger -16 AN (1") port down to a -12 AN (3/4") line, making it essential for engine builds where precise port matching is critical.

Engineered with Allstar Performance's commitment to precision manufacturing, the Reducer AN Male -12 to -16 is constructed from lightweight aluminum alloy, ensuring full flow integrity and leak-free performance under sustained fuel pressure and coolant circulation. The male AN threads on both ports allow for direct connection to female AN ports on various components without the need for additional adapters.

Mechanics and fabricators will find this reducer particularly beneficial when upgrading carbureted or TPI fuel systems to EFI, downsizing coolant passages during radiator relocation, or installing aftermarket fuel cells with non-standard port sizes. Its compact design fits well in tight engine bay configurations, making it ideal for late-model swaps and tube-chassis builds.
