Adapter Fitting Bulkhead Straight 10an

The EARLS Adapter Fitting Bulkhead Straight 10AN is a precision-engineered hydraulic line connector designed for high-performance fuel and coolant systems in modified vehicles. This straight bulkhead adapter serves as a critical junction point in custom fuel injection, nitrous oxide, and turbo cooling circuits where reliability and leak-free operation are essential. Whether you're building a street machine, drag racer, or engine swap platform, this fitting delivers the secure, repeatable connection that separates amateur installations from professional-grade work.

EARLS fittings are manufactured from billet aluminum with anodized finishes that resist corrosion in engine bays and fuel cells alike. The 10AN port size (5/8-inch SAE) accepts industry-standard hose sizes, allowing straightforward integration into existing fuel rails, coolant manifolds, or remote filter mounts. The bulkhead straight configuration means the fitting threads into a panel or manifold body while accepting male hose ends on both sides—eliminating the need for external adapters and reducing potential leak points.

Precision-machined sealing surfaces and O-ring compatibility ensure repeatable, vibration-resistant connections across thermal cycles and high-pressure transients common in forced-induction and modified fuel systems. Technicians and engine builders rely on EARLS fittings for fuel cell installations, turbo coolant bypass setups, and custom manifold fabrication where OEM fittings don't exist. This fitting is an essential component for anyone looking to enhance their vehicle's performance and reliability.
