## Overview

The Dorman 800-413HP Metal Heater Hose Connector is a direct OE replacement designed for select Cadillac, Chevrolet, and GMC vehicles. Crafted from rugged metal, it offers superior heat and abrasion resistance compared to original plastic connectors, ensuring a longer-lasting, leak-free HVAC cooling hose connection. Precision-engineered and pressure-tested, this connector guarantees a seamless fit and reliable performance, backed by a limited lifetime warranty.

## Description

When the plastic original equipment HVAC cooling hose quick connector becomes brittle from heat and abrasion, and cracks, leaks and breaks free from the cooling hose, the dealership solution is a similar plastic replacement. Avoid a similar future failure by upgrading your repair with this more rugged Dorman OE FIX metal connector. Designed to match the performance of the factory design but engineered to far exceed its service life, this sturdy and reliable replacement connector is manufactured to precise standards for a seamless fit on specified Cadillac, Chevrolet and GMC vehicles.

Review: just works - Machining and material quality were better than expected. Edges were clean with no burrs, and the dimensions were consistent — everything lined up without needing to force or modify anything. The material feels like proper spec, not soft alloy, and it handled torque without deforming. Installed smoothly and performed exactly as intended under real load. Solid, reliable part if you’re doing actual mechanical work
Review: Great Upgrade - I love that this is metal vs. the plastic factory ones. Fits like OEM. Let’s just hope the quality of the o-ring is good and lasts a while. Only time will tell. For now, this is working great with no leaks.

Utilized this to upgrade my truck's cheap plastic heater hose connections. Very solid and reliable. No more worries of coolant leaking out at cheap oem failure points. Very easy to install and highly recommended.
