1-3/4in Alloy Hose Joinr

The SAMCO SPORT 1-3/4in Alloy Hose Joiner is a precision straight hose adapter engineered for high-performance cooling and fluid transfer systems. This fitting connects two 1-3/4 inch hose barbs in a direct through-flow configuration, making it ideal for custom automotive cooling applications, motorsport builds, and industrial fluid line assemblies where space-efficient, leak-free connections are critical.

Constructed from lightweight aluminum with a polished finish, this adapter features dual 2.0 mm hose barbs—the raised lip profile that seats into reinforced hose clamps to prevent slip and separation under pressure cycling. The aluminum construction delivers an optimal balance of thermal conductivity and corrosion resistance compared to brass alternatives, particularly valuable in cooling systems where temperature fluctuations demand material stability. The polished surface finish reduces turbulence at the fluid interface and resists oxidation during extended service.

This joiner suits builders of street rods, race cars, marine engines, and motorsport cooling circuits where OEM hose configurations require custom routing or modification. Engine bay space constraints frequently demand compact adapter solutions, and the straight configuration eliminates flow restriction compared to angled fittings. Single-unit packaging makes it suitable for repair, replacement, or integration into modular cooling line assemblies.

SAMCO Sport is recognized in motorsport circles for hose and adapter quality. This fitting integrates seamlessly into systems using standard 1-3/4" diameter hose. Verification of hose OD and barb seat compatibility with your clamp hardware is recommended before installation to ensure proper sealing under operating pressure.
