A/C Hoses and Fittings for Freightliner

You cannot have air condition without the proper hoses and fittings. Luckily with a wide selection of A/C hoses and fittings for Freightliner, you can find what you need to keep you’re a/C in working order.

What does an A/C hose do?

A/C hoses carry refrigerant throughout the air conditioning system. These lines usually come in bundles of four on compact and sedan automobiles and may increase in number depending on the size of the A/C system. The A/C system’s hoses connect to the evaporator, condenser, dryer, and compressor portions of the system.

How do you troubleshoot A/C hose problems on a Freightliner?

Even though the Freightliner is larger than the average vehicle, detecting problems with hoses and fittings in the system is pretty much the same processes for both. You can do the following to troubleshoot issues:

  • Turn on the truck and let it warm up to its normal temperature.
  • Turn the fan speed on a low setting and set the AC system to its coldest temperature.
  • Leave the AC on its cold setting and turn the fan on high mode.
  • Check underneath the vehicle for signs of coolant leaking. Leaking coolant is a sign that hoses or fittings may need to be replaced.
What is a suction hose in a Freightliner A/C system?

The suction hose of an A/C system is also known as the systems cold line because it carries refrigerant to the compressor from the evaporator at abnormally low temperatures. It is because of its role in transferring refrigerant at lower pressure that the suction hose is considerably large on an AC unit.

What is a hydraulic hose used for on a Freightliner?

A hydraulic hose is typically used instead of pipes and tubes. Some manufacturers may put these accessories in place of traditional parts when flexibility is needed for the machine to function correctly. A hydraulic hose is usually composed of rubber and steel, which is formulated in layers for better durability.

What method can be used to measuring hydraulic fittings?

The best way to measure hydraulic fittings is to use a thread pitch gauge, which provides the distance between each thread. Measurements are given in metric connections when you place the indicator on the threads so that the fitting is tight. Match the results on a reliable table to get the most from your hydraulic fitting.

How do you make a hose assembly on a Freightliner?

You can make a hose assembly on a Freightliner by doing the following:

  1. Gather all of the tools needed for the project.
  2. Measure the hose and cut it for fitting.
  3. Pick out the desired fitting.
  4. Mark the insertion depth before pushing in the hose.
  5. Verify and adjust crimper settings.
  6. Select the die and put the hose inside the machine.
  7. Set the compression ring and crimp the hose. Verify the diameter thereafter.
  8. Clean the hose system before capping it.
