1-1/2in to 1-3/4in Inch Hose Barb Splice Coupler

The ICT BILLET 1-1/2in to 1-3/4in Inch Hose Barb Splice Coupler (AN627-28-24A) is a straight fitting adapter designed to connect hoses of different diameters in hydraulic, pneumatic, and fluid transfer systems. This aluminum coupler bridges a 1-1/2 inch barbed connection to a 1-3/4 inch barbed connection, making it essential for applications where hose sizing transitions are necessary without additional connectors or adapters.

Constructed from aluminum and finished with natural anodizing, this hose barb splice coupler offers corrosion resistance suitable for marine, industrial, and automotive environments. The natural anodized finish protects the aluminum substrate while maintaining a clean aesthetic appearance. The barbed design on both ends ensures positive engagement with hose clamps, creating a secure seal that resists vibration-induced loosening. The straight configuration allows for direct flow path alignment, minimizing turbulence and pressure drop in high-flow applications.

This fitting is ideal for custom fluid systems where sizing flexibility is critical—from cooling loops and fuel transfer systems to pneumatic tool setups and hydraulic brake line assemblies. The 1-1/2in to 1-3/4in transition accommodates off-the-shelf hose stock while minimizing inventory complexity. Compact at 2 x 1.5 x 3 inches and weighing just 0.14 lbs, it integrates easily into tight spaces without adding significant bulk to system layouts.

When selecting a hose barb splice coupler, material durability and corrosion protection directly impact system longevity in demanding environments. Aluminum couplers like this AN627-28-24A model are preferred in applications where weight savings matter and galvanic isolation from steel components is beneficial. Proper hose clamp selection and secure clamping technique ensure maximum holding power and leak-free operation throughout the product's service life.
