Bulkhead AN -4 Tee On The Side

The ALLSTAR PERFORMANCE Bulkhead AN-4 Tee fitting is a three-way aluminum adapter designed for high-flow fluid and fuel line distribution in high-performance racing and motorsports applications. This black anodized bulkhead tee connects three separate 4 AN male lines simultaneously, making it essential for fuel injection systems, cooling circuits, and pressurized fluid management where multiple outlets from a single point are required.

Constructed from aluminum and finished in black anodize, this fitting provides corrosion resistance critical for engine bay environments exposed to fuel vapors, moisture, and thermal cycling. The tee configuration offers one inlet and two outlets (or vice versa), allowing builders to split or combine fluid flows while maintaining the integrity of sealed systems. All three ports accept 4 AN male connectors, ensuring compatibility with standard -4 hose assemblies and related adapter fittings commonly found in race car fuel systems and custom high-flow cooling setups.

This fitting is ideal for engine builders, fabricators, and motorsports enthusiasts constructing fuel distribution manifolds, dual-circuit cooling systems, or custom plumbing layouts where space is limited and a compact tee junction is required. The bulkhead design means it can be mounted directly to a panel, firewall, or custom bracket, eliminating the need for additional support structures. ALLSTAR PERFORMANCE fittings are engineered to handle the flow rates and pressures typical in street and competition racing applications.

AN-4 threaded fittings are a standard across the motorsports industry, allowing this tee to integrate seamlessly into existing fuel systems and custom installations. Whether building a new race car fuel cell system, upgrading to a dual-fuel-pump configuration, or adding auxiliary coolers, this aluminum tee provides a reliable, flow-efficient junction point.
