-4m To -3m Flare Rdcr

The XRP -4m To -3m Flare Reducer is a precision AN adapter designed for high-performance fuel, coolant, and hydraulic system plumbing in race vehicles and modified street cars. This compact reducer bridges two different AN port sizes, stepping down from -4 AN (1/4" nominal) to -3 AN (3/16" nominal), making it essential for custom fuel rail builds and turbo coolant lines.

Engine builders and fabricators rely on this reducer to eliminate the need for custom hose lengths or undersized lines that could compromise flow or safety. The flare-end design (37° JIC flare standard) ensures leak-free connections when properly torqued and fitted with matching hose or hard-line assemblies. Its compact dimensions allow for installation in tight engine bays where space is limited.

Experienced mechanics and fabricators building custom fuel systems and coolant overflow circuits will find this reducer indispensable for matching incompatible port sizes. It is suitable for use with various media, including gasoline, diesel, and coolant, ensuring versatility in different applications.
