1-3/4in Rad. Hose Fitting Red

The 1-3/4in Rad. Hose Fitting Red by SPECTRE is a precision-engineered worm gear hose clamp designed for automotive cooling systems, fuel lines, and other fluid transfer applications where secure, dependable clamping is essential. Built for professionals and enthusiasts who demand reliable performance under vibration and temperature cycling, this red anodized aluminum fitting delivers the corrosion resistance and visual identification that modern engine bays require. Whether you're performing routine maintenance or custom cooling system modifications, this hose fitting provides the engineered reliability that keeps systems sealed tight.

Manufactured from aluminum and finished in red anodized coating, the 1-3/4in Rad. Hose Fitting Red features a hex-drive worm gear mechanism that enables precise, controlled tightening without over-torquing or slippage. The worm gear design distributes clamping force evenly around the hose circumference, preventing deformation while maintaining a consistent seal across the full diameter. Red anodizing not only enhances corrosion resistance against coolant, oils, and salt spray—it also provides easy visual identification of clamp size and condition during inspections and routine maintenance checks, reducing downtime and installation errors.

This clamp is ideal for 1-3/4 inch diameter hose applications commonly found in radiator connections, heater hose routing, and custom cooling loops. Installers benefit from the hex-drive interface, which accepts standard hex sockets or wrenches for repeatable, tool-independent tightening in tight engine compartment spaces. Individual unit packaging ensures you receive the exact quantity needed without waste, making it suitable for single-system repairs or small-batch assembly work where precision and reliability are non-negotiable.
