#12 Str Push-On Hose End

The #12 Str Push-On Hose End (MPN 230012) is a critical fitting component designed for high-performance fuel, oil, and coolant system plumbing in modified and race vehicles. Whether you're building a custom fuel system for a turbo engine, upgrading your cooling circuit on a high-horsepower application, or fabricating a complete fuel delivery upgrade, this straight push-on hose end provides the secure, leak-free connection modern automotive enthusiasts and professional mechanics demand. Push-on hose ends eliminate the need for clamps and hose barbs that can slip under pressure, offering superior reliability in demanding under-hood environments.

Constructed from anodized aluminum in a choice of blue or red finishes, the #12 Str Push-On Hose End features a 12 AN hose barb inlet and 12 AN female thread outlet, delivering a true 12 AN connection on both sides. The straight configuration eliminates unnecessary bends and reduces turbulence, critical when managing high-flow fuel delivery or pressurized coolant systems. AN (Army-Navy) size 12 corresponds to 3/4-inch nominal hose diameter, making this fitting ideal for primary fuel lines, return lines, and cooling applications on engines producing 500+ horsepower. The push-on barb design grips hose firmly without sharp edges, reducing wear and ensuring a permanent mechanical lock that won't spin out during vibration or aggressive driving.

This fitting is indispensable for engine builders, suspension tuners, and DIY enthusiasts upgrading fuel systems, coolant circuits, or power steering applications on street machines, circle track cars, and weekend warriors. Install the push-on hose end by sliding your hose over the barb until it seats fully—no clamps required, though some builders prefer secondary safety clamps on critical fuel lines for redundancy. The compact 2.7 x 1.4 x 4-inch footprint fits tight engine bays and custom fabrication scenarios where space is limited. Pair multiple #12 Str Push-On Hose Ends throughout your plumbing system to ensure a cohesive, professional appearance and consistent, reliable performance under boost, heat, and extended track sessions.
