#10 x 5/8 Hose Barb Fitting Black

The #10 x 5/8 Hose Barb Fitting Black from FRAGOLA is a critical fluid transfer component engineered for custom automotive cooling, fuel, and hydraulic systems. This fitting is purpose-built for mechanics and fabricators who demand secure, reliable connections in high-performance engine builds, LS swaps, custom water cooling loops, and modified brake systems. When you're investing in precision engine work, substandard fittings create leaks, pressure loss, and potential catastrophic failure—this barb design eliminates those risks with proven FRAGOLA engineering.

Constructed with a barbed stem design, this #10 fitting accepts standard hose sizes and creates a mechanical lock when properly secured with a clamp, preventing slippage under vibration and pressure cycling common in high-RPM applications. The black finish provides corrosion resistance and durability in engine bay environments, while the compact 5/8-inch barb length accommodates tight installation spaces typical of modified engine compartments. FRAGOLA's precision manufacturing ensures consistent bore sizing and barb geometry, which are critical for maintaining system integrity when operating high-flow cooling or pressurized fuel systems at elevated temperatures.

Professional mechanics and serious DIY builders rely on this fitting for LS engine conversions, turbocharged system plumbing, and custom radiator configurations where OEM fittings don't fit the modified layout. Installation requires compatible SAE hose rated for your application's pressure and temperature—pair this with quality stainless steel or worm-gear clamps to ensure vibration doesn't loosen the connection. Whether you're routing coolant through a custom water jacket, upgrading fuel delivery on a modified engine, or installing hydraulic assist systems, this FRAGOLA barb fitting delivers the secure, leak-free performance your build demands.
