1.75in Hose W/P Fitting Red

The 1.75in Hose W/P Fitting Red is a precision water pump inlet adapter engineered for high-performance cooling systems on Meziere 100 Series water pumps. Built for engine builders, race mechanics, and serious enthusiasts upgrading to aftermarket water pumps, this straight fitting bridges the gap between your custom hose routing and pump inlet without compression loss. Whether you're building a street engine, track car, or daily driver with modified cooling architecture, this aluminum fitting ensures reliable flow and leak-free operation under sustained boost and high RPM conditions.

Constructed from red anodized aluminum, the 1.75in Hose W/P Fitting features a 1 in NPT male thread on one end and a 1-3/4 in hose barb on the other, allowing secure connection to standard silicone or braided coolant hose without clamps or secondary adapters. The straight-through design minimizes turbulence and maintains consistent water pressure distribution, critical when running tight cooling tolerances on forced-induction or high-displacement builds. The red anodized finish provides corrosion resistance while matching Meziere's aesthetic, and the 0.31 lb aluminum construction keeps underhood weight minimal—important on weight-sensitive platforms. The barbed outlet accommodates 1.75-inch inner diameter hose, a common sizing in custom cooling loops where standard OEM fittings don't align with your plumbing configuration.

This fitting is essential for anyone running a Meziere 100 Series aftermarket water pump in a custom engine bay layout, including LS, small-block Chevy, and other platforms with non-stock pump mounting. It's particularly valuable when transitioning from cast-iron factory cooling passages to flexible hose routing, eliminating the need for expensive custom fabrication. Installation requires only a wrench for the NPT port and hose clamps at the barbed outlet; no special tools or machine work needed. Buy this 1.75in Hose W/P Fitting Red to maintain system integrity, prevent cooling bypass, and ensure your upgraded pump delivers full flow to the engine block.
