Fitting - Electric Water Pump 3/4 NPT x 1.75 Hose

The Fitting – Electric Water Pump 3/4 NPT x 1.75 Hose from PRW Industries is a straight adapter designed to connect 3/4 inch NPT male threads to a 1.75 inch hose barb. This aluminum fitting with clear anodized finish is engineered specifically for electric water pump installations where reliable coolant flow and vibration resistance are critical. The compact design and lightweight construction make it an ideal choice for engine cooling systems in high-performance and custom applications.

The 3/4 NPT male thread standard ensures compatibility with typical water pump ports and manifold fittings across automotive cooling systems. The hose barb configuration provides a secure mechanical grip on 1.75 inch diameter hose without requiring a separate hose clamp, though many installers add a stainless steel clamp for additional security in high-vibration environments. Aluminum construction offers excellent thermal conductivity and corrosion resistance, particularly important in coolant-filled systems where galvanic compatibility with the surrounding materials matters. The clear anodized finish adds a protective oxide layer that resists oxidation and maintains appearance over extended engine bay exposure.

This fitting is suited for builders and technicians working with electric water pump conversions, racing engine builds, and custom cooling system layouts where flow path optimization requires precision adapters. It bridges standard NPT threaded connections to modern hose barb systems, eliminating the need for multiple adapter stages. The straight design eliminates flow turbulence and pressure drop that can occur with angled fittings, keeping coolant temperatures stable during sustained high-load operation.

PRW Industries is recognized in the performance cooling market for precision-engineered fittings and water pump solutions. This adapter fits within the broader category of electric water pump accessories and cooling system adapters, where thread size standardization and hose compatibility determine system reliability. Whether upgrading a fuel-injected engine bay or engineering a complete custom cooling loop, this 3/4 NPT to 1.75 hose barb fitting delivers verified thread and barb dimensions for confident installation.
