5/8in Hose Barb .625in Splice Coupler

The 5/8in Hose Barb .625in Splice Coupler by ICT BILLET is a precision-engineered fitting designed for fuel system, coolant, and hydraulic line connections in high-performance and stock vehicle applications. This essential component allows for the joining of hoses of matching diameter without the bulk of traditional clamp-style connections. Whether you're assembling a fuel injection system or upgrading coolant routing, this splice coupler ensures reliable leak-free performance.

Manufactured from billet aluminum, the AN627-10A coupling features a single 5/8-inch hose barb port that accepts 5/8-inch ID hose for secure, vibration-resistant sealing without additional hardware. The barbed design creates a mechanical lock when the hose is pushed onto the fitting, allowing pressure from fuel or coolant to compress the hose onto the barbs—a time-tested method used across motorsports and OEM applications.

Builders of street rods, turbocharged platforms, and custom cooling systems rely on ICT BILLET couplers for their consistency and corrosion resistance. This fitting is compatible with any 5/8-inch braided or reinforced hose, making it a versatile choice for various applications.
