1-1/4 to 1-1/2 Hose w/ 1/8NPT Steam Port Adapt

The 1-1/4 to 1-1/2 hose with 1/8NPT steam port adapter from ICT Billet is designed for custom cooling system builds where space efficiency and precise fluid routing are essential. This transition adapter effectively bridges two common hose diameters while integrating a dedicated steam port connection, making it suitable for various applications, including street engines and engine swaps.

Constructed from lightweight and thermally stable billet aluminum, the adapter provides a rigid, one-piece interface. The stepped bore transitions from 1-1/4 inch to 1-1/2 inch diameter, accommodating standard hose sizes used in both OEM and custom cooling circuits. The 1/8NPT steam port tapping allows for direct connection of steam sensors or auxiliary cooling ports, which is crucial for managing coolant temperature and preventing vapor lock.

This adapter is ideal for fabricators, engine builders, and enthusiasts working on custom water pumps, radiator relocations, or late-model engine swaps into older platforms. It is designed to meet the needs of those who require efficient cooling solutions without the need for custom fabrication or bulky clamps.
