1-3/4in Rad. Hose Fitting Red

The 1-3/4in Rad. Hose Fitting Red by SPECTRE is a precision-engineered radiator hose connector designed for custom cooling system builds and engine modifications. This fitting serves as a critical junction point in your vehicle's coolant circuit, allowing you to route hoses with precision and flexibility during intake manifold work, engine bay reorganization, or high-performance cooling upgrades.

Whether you're fabricating a custom water pump setup or integrating aftermarket radiators into a modified engine bay, this brass-body fitting delivers the durability and reliability that serious enthusiasts demand. The precisely machined internal passages ensure minimal flow restriction, critical for maintaining optimal coolant circulation and preventing hot spots in modified engines.

This radiator hose fitting is ideal for builders and mechanics customizing street rods, drag race platforms, and turbocharged or supercharged vehicles requiring non-standard cooling layouts. SPECTRE's manufacturing standards guarantee tight tolerances and secure sealing, essential when working with pressurized cooling systems where hose blow-offs or leaks can cause catastrophic engine damage during track events or spirited driving.
