#3 AN Bulkhead Tee On The Run

The #3 AN Bulkhead Tee On The Run from Triple X Race Components is a compact hydraulic fitting designed for high-performance fuel, oil, and coolant systems in racing and street performance vehicles. Built for engine builders and dedicated enthusiasts who demand reliability in tight underhood spaces, this bulkhead tee functions as a three-way junction block that allows simultaneous fluid distribution or consolidation without compromising flow integrity. Whether you're plumbing a dry-sump system, cooling circuit modification, or fuel rail setup, this fitting eliminates the need for multiple separate connections and reduces leak points.

Triple X Race Components engineers this bulkhead tee with precision machining to #3 AN (1/4-inch) port specifications, ensuring ISO 6149 thread compatibility and repeatable, leak-free seals under sustained pressure and thermal cycling. The compact profile—measuring just 2.4 inches across—fits into congested engine bays where traditional braided line configurations would create packaging conflicts. Aluminum construction keeps weight negligible at 0.03 lbs while maintaining strength required for boost-era fuel systems and high-volume cooling applications. The on-the-run designation emphasizes field-proven durability and quick assembly without requiring special tools or adapters.

This fitting serves engine swaps, turbocharger installations, and custom cooling solutions where OEM hard-line geometry doesn't accommodate your modified layout. Fabricators and race teams rely on bulkhead tees like this to consolidate remote oil cooler returns, split fuel delivery to dual injector stages, or stage coolant flow through multiple block ports. The #3 AN size handles flows typical of naturally aspirated and moderately boosted engines; verify inlet/outlet pressure ratings and flow requirements against your specific system demands before installation. Pair with quality braided steel lines, proper AN fittings, and thread sealant rated for your fluid type to ensure years of vibration-free service.
