Gates 19830 HVAC Heater Hose - Engine To Heater or Lower

Gates Molded Heater Hose 19830 Overview

The Gates 19830 molded heater hose is an OEM-style coolant hose built for tight engine compartments where a straight hose will not route cleanly. Made from EPDM and factory-molded to its shape, it supports coolant, water, and air transfer and is also approved for marine applications.

The 19830 part number is a direct reference for buyers searching for a molded heater hose with the correct 19 mm inside diameter at both ends and a 20.6-inch centerline length.
