1.75in Hose W/P Fitting Polished

The Meziere 1.75in Hose with Polished Fitting (Part No. WP1175U) is a precision water pump hose connector engineered for high-performance cooling systems. This straight fitting transitions from a 1 inch NPT male thread to a 1-3/4 inch hose barb, delivering reliable coolant flow in demanding automotive applications. Constructed from aluminum and polished to a professional finish, this fitting is optimized for Meziere 100 Series water pumps and compatible cooling system configurations where clean aesthetics and dependable hydraulic connection are essential.

The 1 NPT male inlet threads into standard pump ports with positive engagement, while the hose barb outlet accommodates 1-3/4 inch hose diameter—a sizing that balances coolant velocity with pressure drop across the circuit. The straight-through design minimizes turbulence and maintains optimal flow rates critical for heat rejection in high-displacement or supercharged engine builds. The polished aluminum construction resists corrosion in typical engine bay environments while remaining lightweight, contributing to reduced overall system weight. The barbed outlet design ensures hose retention without the need for secondary mechanical clamps, though using hose clamps is recommended for maximum security during extended high-vibration operation.

This fitting addresses the cooling requirements of street, strip, and race engine builders who demand quality components from established manufacturers. Owners of vehicles equipped with Meziere electric or mechanical water pumps rely on matched fittings to ensure proper system architecture and prevent coolant leaks at connection points. The polished finish suits engine compartments where visibility and appearance are factored into build aesthetics, common in show vehicles and pro-touring builds where function meets finish presentation.

Cooling system integrity depends on precise connections between components. Selecting OEM-equivalent fittings from the same manufacturer as your water pump eliminates compatibility guesswork and ensures thread pitch, barb diameter, and material compatibility are confirmed. The WP1175U represents that level of specification certainty for builders committed to reliable, long-term performance.
