Inline Tube Replacement for 1968-72 GM AC Heater Box

The 1968-72 GM A-body models, including the Elcamino, were equipped with a specific heater box and heater core tube seal. This seal is designed to go around the face of the heater core tubes within the heater box, providing a crucial sealing function.

The heater box is a crucial component of the vehicle's heating and ventilation system, responsible for distributing warm air throughout the cabin. The heater core, situated within the heater box, is responsible for heating the air that is then circulated into the interior of the vehicle.

The heater core tube seal plays a vital role in ensuring the efficient and effective operation of the heating system. This seal is made of a black foam material and is designed to create a tight seal around the heater core tubes, preventing air leaks and ensuring that the warm air generated by the heater core is directed into the cabin as intended.

Without a properly functioning heater core tube seal, the heating system may experience air leaks, resulting in reduced heating efficiency and decreased cabin comfort for the occupants. This seal helps to maintain the integrity of the heating system, ensuring that the warm air is directed where it is needed most.

The 1968-72 GM A-body models, which include the iconic Elcamino, were designed with a specific heater box and heater core tube seal configuration to meet the heating and ventilation needs of these vehicles. The black foam seal is an essential component that helps to keep the heating system operating at its best, providing warmth and comfort to the driver and passengers.

Overall, the heater core tube seal is a critical part of the 1968-72 GM A-body's heating system, ensuring that the warm air generated by the heater core is effectively distributed throughout the cabin. Its proper function and maintenance are essential for maintaining the vehicle's heating capabilities and providing a comfortable driving experience.
