Performance Fittings Adapter -4 ORB to -4 AN 920-04

The Performance Fittings Adapter 920-04 is a straight fitting designed to connect -4 ORB (O-Ring Boss) to -4 AN lines, providing a secure and leak-free connection for fluid transfer systems in automotive and racing applications. Constructed from high-quality aluminum, this adapter is lightweight yet durable, and is suitable for use in fuel, oil, coolant, and hydraulic lines. Its precision-machined threads ensure a reliable fit, making it an essential component for custom plumbing setups or repairs. The adapter is commonly used in performance vehicles, race cars, and other high-demand automotive environments where robust and versatile fittings are required.

Sized specifically for -4 ORB to -4 AN transitions, this adapter lets you connect straight-thread ORB ports — common on pumps, filters, and fuel rails — to AN-flare hose ends and fittings without adapting the whole system. The blue anodized aluminum body resists the fuel, oil, and coolant exposure typical of engine bay plumbing, and because the O-ring is included, it is ready to install straight out of the package.
