AN Expander #8 Female x #10 Male

The AN Expander #8 Female x #10 Male from Triple X Race Components is a precision hydraulic or fuel line adapter designed for high-performance racing and custom automotive builds. This fitting connects #8 female ports to #10 male ports, making it ideal for tight engine bay configurations where direct hose routing is not feasible. Whether you are plumbing a fuel system, coolant loop, or hydraulic circuit, this expander provides the necessary flexibility to optimize line geometry and minimize kinks that can compromise flow.

Manufactured to strict OEM tolerances, the AN Expander features a stepped internal bore design that ensures a smooth transition between the #8 and #10 AN specifications. This design preserves flow characteristics while eliminating turbulence at the junction. The black anodized aluminum construction resists corrosion and maintains structural integrity under pressure spikes, especially relevant in forced-induction applications where fuel or coolant systems experience elevated demand.

Engine builders and fabricators working with mixed-size AN systems or retrofitting performance applications will find this expander essential. Its compact design and minimal weight make it suitable for space-constrained engine bays where every millimeter of real estate matters. The straightforward female-to-male configuration integrates seamlessly into existing modular hose assemblies, ensuring a reliable connection.
