2.5in Hose Barb Coupler

The 2.5in Hose Barb Coupler from ICT BILLET is a straight adapter fitting designed to connect two 2.5-inch hose barb lines with a secure, leak-free junction. Built for high-performance cooling systems, fuel delivery circuits, and custom hydraulic applications, this coupler serves mechanics and fabricators who demand reliable fluid transfer in modified or racing vehicles. Whether you're plumbing a custom radiator setup, upgrading your intercooler ducting, or assembling a bespoke fuel system, a quality hose barb coupler is essential to prevent pressure loss and contamination.

Machined from aluminum and finished in natural anodized coating, the AN627-40A delivers corrosion resistance and durability in both engine bay and underbody environments. The barbed design on both ends grips hose material firmly, reducing slippage under pressure and vibration—critical when managing high-flow applications in turbocharged or supercharged builds. The straight-through geometry minimizes flow restriction, maintaining system efficiency across coolant, boost air, and fuel circuits. At just 0.13 lbs, this compact fitting (2.5 x 2 x 2.5 inches) integrates cleanly into tight engine compartments without adding unnecessary weight or complexity.

Professional installers, shade-tree builders, and performance shops rely on ICT BILLET hose barb couplers for custom cooling loops, forced-induction charge-air piping, and fuel system modifications on street and track vehicles. Verify hose wall thickness and clamp compatibility before installation; reinforced silicone or braided hose rated for your system pressure ensures optimal performance and safety. This fitting pairs seamlessly with standard hose clamps and integrates into any 2.5-inch barb plumbing scheme, making it indispensable for DIY engine swaps, radiator upgrades, and competitive motorsports builds.
