New direct replacement air conditioning liquid line & hose set for all 1976-79 Ford F Series trucks & 78-79 Broncos with factory installed A/C.

This is the set that connects the filter-drier in front of the radiator support (via the line) to the expansion valve (via the hose) at the firewall. Direct fit replacement made with modern barrier style hose which is compatible with both R12 and 134a.

This new set does away with the sightglass and quick disconnect fittings, which eliminates possible leak points from the line to the hose.

CONVERTING MY FORD TO 134a

Until 1995, most cars with air conditioning used R-12 Freon refrigerant that is said to have a negative side effect of damaging the ozone layer and is no longer produced in most countries. since then, the industry standard has been R134a, which is an efficient replacement.  Contrary to popular belief, most cars originally equipped with R-12 can be converted to 134a and still keep you just as cool.

Systems w/o Suction Valve
Minimum Requirements

  • Change or restore the filter-drier.
  • Drain the compressor oil and recharge with 134a compatible oil. (PAG or Ester Oil)
  • Insure that the system is clean and free of contaminants (Depending on component condition, this may be a simple matter of blowing out with compressed air or liquid flushing with an air-conditioning flushing agent)
  • Replace or restore all rubber hoses with barrier hose.
  • Install 134a charge port adapters.
  • Charge with 134a between 70-80% of the original R12 charge amount.
  • Replace any o-rings with 134a compatible.

HELPFUL HINTS

  • Ignore the sight-glass. A properly charged 134a system will likely show bubbles in the sight-glass.
  • Typical 134a charge rate will be approximately 70-80% of the factory R12 charge amount.
