Vacuum Harness HVAC: Description and Operation
DESCRIPTION
Engine vacuum systems are currently installed as a pre-assembled color coded type of harness. The colorings act as a visual aid both during
production and during service.
Nylon Vacuum Harness Tubing And Connectors
CONSTRUCTION
The vacuum hose harness consist of colored nylon tubing (0.15" o.d. and 0.09" i.d.) bonded to nylon or rubber connectors.
A rubber insert is installed in the end of the nylon connectors to provide a secure fitting seal at the components nipple connection.
Occasionally, rubber hosing (5/32" or 7/32") may used within the harness to replace a damaged nylon vacuum tube.
