Repair any rear A/C line!
Unique repair kits mean
Never any special tools!
Never any crimping! :
No Special Tools or Crimps Required!
Repair any rear A/C line on vans, minivans, suv's and suburbans! Rear A/C units have become very popular in vans, minivans, suv's and suburbans. The addition of the rear evaporator creates a unique A/C repair problem. That is, the lines for the refrigerant typically run under the vehicle and are exposed to all the harsh elements all the time. They quickly rust or corrode and become a major source for refrigerant (freon) leaks in the A/C system.
Until now, the only easy repair was to purchase replacement lines from the dealer. Installation wasn't really easy and the parts can be very expensive too. Now, there is a professional way to repair those rear A/C lines without using andy special tools or crimping.

How do the line kits work?
Here's a look under a typical minivan where the rear A/C lines are completely exposed to all the elements. Because they are exposed, the rear A/C lines have become a major source of refrigerant leaks in A/C systems that have rear evaporators. Until now, the only repair was to replace the entire line from the dealer. Now, rear A/C line repair kits let you repair any line without any special tools or crimping! Rear A/C lines on vans, suv's and suburbans are exposed to all the elements of the weather!

How do the A/C Line Repair kits work?
Are they easy to install?
Step One:
With the A/C system discharged, cut the line section that is rusted, damaged or corroded. Always use a tube cutter so that the line ends will be free of rough edges and burrs.

Step Two:
Install the nut and ferrule (with the narrow end towards the nut as shown in the illustration below). DO NOT INSTALL THE O-RING at this time. Push the line into the tube union until it bottoms out. Tighten the nut to 10-12 ft.lbs. of toque. Then loosen the nut and remove the tube. The ferrule should now be compressed onto the tube. It's important to do this step first. So many times the service technician installs the nut, ferrule and o-ring all at once and tightens the fitting. That changes the location of the ferrule and will cause the union to leak.

Step Three:
Now install the o-ring (against the ferrule), insert the tube into the union bottoming out the tube, and tighten the nut. You've just completed a professional leak free tube union. Now repeat Steps 1 thru 3 for the opposite side!

Rear A/C Line repair kits are easy to install without any special tools or crimping!
