Detailed Product Description

The Dorman 800-411 HVAC Heater Hose Connector is engineered to maintain the integrity of the vehicle’s heating system by providing a secure and leak-resistant connection between heater hoses. Constructed from plastic, this connector offers resistance to corrosion and heat exposure common in HVAC systems. The straight fitting angle ensures a direct and unobstructed flow path, reducing the risk of kinks or flow restrictions. One end features a quick disconnect fitting, allowing for fast and tool-free removal during repairs or maintenance, while the other end uses a hose barb fitting to firmly secure the hose in place. Both ends are sized at 3/4 inch, making this connector suitable for a wide range of heater hose applications in vehicles such as the Buick Achieva, Chevrolet Colorado, Ford F-250 Super Duty, and Pontiac Grand Am.
