Vacuum Harness HVAC: Description and Operation

Mini-tube vacuum hoses are provided in the vacuum hose harness assemblies. They provide greater flexibility with less tendency to collapse and are less susceptible to pinching. Service of damaged hoses is easily performed by using a short piece of standard 3 mm (118 inch) Inner Diameter (ID) vacuum hose and inserting the cut ends of the mini-tube into the ends of the standard 3 mm (1/8 inch) ID vacuum hose.
