Autoplumb offers numerous components to convert your rubber heater hose and clamps to AN style fittings and hose.
Two options available:
Use tube adapters to connect to existing heater core tubes that exit from the firewall. Removal of the tubes barb is required and the tubing must be the appropriate size for the selected adapter. It is necessary for a minimum of 1" of tubing to be exposed to facilitate the installation of the tube adapter.
Our firewall bulkhead converts to -10AN on the engine side with the use of our AN o-ring adapter. Attach the passenger compartment side to your heater core using the 5/8" barbs.
These methods work well in many situations. It is the responsibility of the user to determine suitability for their specific application.
