Adapter Fittings -4 to 7/16-20 10pk

The ALLSTAR PERFORMANCE Adapter Fittings -4 to 7/16-20 10-pack (ALL50032-10) is an essential component for custom fuel, oil, and brake line fabrication in street rods, race cars, and modified performance builds. These adapters bridge the gap between AN-4 and 7/16-20 thread specifications, allowing mechanics and fabricators to repurpose hose and tubing assemblies without custom ordering or expensive special orders.

The -4 to 7/16-20 configuration provides a smooth transition between AN-4 hose (0.25-inch inner diameter) and 7/16-20 SAE male ports commonly found on carburetors, fuel pumps, and brake proportioning valves. ALLSTAR PERFORMANCE aluminum construction ensures lightweight compatibility with high-flow applications while resisting corrosion in engine bay and underbody environments. The precision SAE threads guarantee leak-free seals with proper torque and PTFE tape application, critical for systems carrying fuel under pressure or brake fluid under extreme thermal cycling.

Experienced fabricators and performance engine builders rely on this adapter pack when converting carbureted fuel systems to fuel injection or standardizing line connections across mixed-source components. The 10-piece set delivers the versatility modern performance shops demand, making it an ideal choice for those looking to adapt legacy equipment to modern -4 fuel rails.
