Hose End #12 Straight

The Hose End #12 Straight from A-1 Products is a precision-engineered hydraulic or pneumatic connector designed for automotive applications where reliable fluid transfer is critical. Whether you're building a custom cooling system, installing aftermarket braking lines, fuel injection upgrades, or modifying suspension components, this straight hose end fitting ensures leak-free connections under pressure. Mechanics and performance enthusiasts rely on quality hose ends to prevent system failures, maintain pressure integrity, and eliminate costly mid-project complications.

The #12 designation refers to the AN (Army-Navy) standard hose size, which is widely adopted across OEM and custom automotive fabrication. This straight configuration eliminates the need for additional elbows or adapters, reducing connection points and potential leak sources in your system. A-1 Products manufactures these fittings to precise tolerances, ensuring a secure seal against industry-standard hoses and ports. The compact design—weighing just 0.18 lbs with dimensions of 2.85 x 1.3 x 4.6 inches—makes it ideal for tight engine bays and complex plumbing layouts common in engine swaps, turbo installations, and custom fabrications.

This hose end suits builders working on high-performance cooling systems, fuel delivery modifications, custom braking circuits, and pneumatic suspension upgrades. Installation is straightforward: match your hose ID to the #12 AN standard, thread the fitting securely, and torque to manufacturer specs to prevent separation under vibration and pressure cycling. Ensure your system's rated working pressure exceeds peak operating conditions. Stock this fitting for repairs, replacements, or new builds where direct-line connections eliminate unnecessary fittings and improve system reliability.
