## Overview

The Dorman 800-409HP Coolant Connector is a precision-engineered stainless steel HVAC heater hose connector designed to replace original plastic parts prone to heat and vibration damage. It offers superior durability, easy installation with exact OE fit, and has passed extensive corrosion, heat, and pressure tests to ensure reliable, long-term performance for select vehicle models.

## Description

HVAC heater hose connectors fail when the plastic material fatigues from heat and vibration. This upgraded Dorman OE FIX replacement connector is made from corrosion-resistant stainless steel for greater durability.

Review: Must have for replacing the plastic factory connectors on Chevy truck - These will not break, very high quality stainless steel items here. Perfect fit and replacement for the cheap plastic factory items. My plastic original connectors lasted 19 years so I shouldn't complain too much, but these steel ones will last forever.
Review: Better than OEM - When I bought my truck I realized it had no heater in the cab. When I started investigating I realized the original heater core adapter had broken so the previous owner bypassed the heater core. Bought 2 of these, they clicked right into place, no leaks, great price and now I have heat in my truck! Great product, highly recommend, fast shipping.
