2″ duct hose tube for extending vent ducting. The tube can be used as a 36″ piece of duct hose or it can be cut down to any size. This tube is ideal for moving air through tight spaces without crushing the down like regular duct hose does. The tube is flat on the inside which allows the air to flow without any resistance. Without resistance the air can travel further without losing as much vent pressure. The tube is great for adding vents to the rear of a vehicle, the headliner, or under the dash from the passenger to the driver side. The tube is oval shaped that fits our 2″ duct hose over it. The tube gets connected to the evaporator or any vent (louver) with 2″ vent (duct) hose. The duct hose can be held on with duct tape or screws.
The tube is made out of 1/8″ abs plastic that is designed with an overlapping assembly. This guarantees no air leaks. For maximum efficiency the tubing can be covered with firewall insulation. This will ensure the cold air stays cold, and the hot air stays out.
The tubing dimension is:
36 inches long
2-1/4 inches wide
1-5/16 inches tall
These dimensions are the tube only, when the duct hose is added at each end it will increase the size.
We designed these tubes for a project in our facility to route airflow through the headliner of a vehicle. They worked very well without loss of airflow and vent temperature. Insulating the tube will ensure better performance, (we do not sell insulation).
