Restore proper airflow and keep your classic Square Body’s HVAC system working like new with this 1973-87 Square Body Chevy & GMC Heater & AC Duct Dash Vent Hose. This black, flexible, heat-resistant hose is a direct fit replacement for the original duct that connects the air vent housing to the far-right dash vent on your truck’s dash pad.
Over time, factory hoses become dry rotted, brittle, or cracked, restricting airflow to your dash vents. This reproduction hose installs just like the original that will simply spin it onto the duct and vent housing for a secure fit. Note: the dash pad must be removed for installation.
Each hose measures 12 inches in length with an inside diameter of 3.25 inches, ensuring proper fitment and function with your factory A/C or heater duct system.
