Constructed from lightweight aluminum and finished in black anodized coating, the AN Expander #16 Female x #20 Male delivers corrosion resistance and durability in demanding underhood environments. The swivel male end allows for ease of installation and minor angle adjustment during final assembly, reducing stress on connected hoses and fittings. The anodized finish not only protects against oxidation and fluid weeping but also provides a professional appearance in visible engine bays.

Race teams, hot rod builders, and serious enthusiasts rely on Triple X Race Components adapters to maintain system integrity at extreme pressures and temperatures. This fitting is ideal for custom fuel delivery systems, high-flow cooling loops, and modular brake architectures where port-size transitions are unavoidable. Installation is straightforward with any standard AN wrench—simply thread the swivel male end into your #20 port and connect your #16 female hose or component to the opposite end. Each adapter is individually tested to ensure leak-free performance, making it a trusted choice for both street and track applications.
