Thanks to an assortment of aftermarket kits, installing air conditioning in a street rod is something that is easy to do for hands-on homebuilders, with one exception—making the necessary hoses. Generally the required hoses and the necessary ends are included, however those ends have to be crimped onto the hose to make a leak-free union. In most cases that means a trip to the local A/C installer, but there is another, more convenient, option from Eastwood: the Mastercool A/C Hose Crimp Set, PN 71550. The crimping kit comes with four sets of dies and is operated manually with a wrench. The sturdy construction and simple operation produces professional-looking, leak-free connections.
As we are in the middle of installing A/C in two of our project cars we decided to order a crimp set and found it easy to use. It comes with the holding fixture assembly, die sets #6 (5/16 inch), #8 (13/32 inch), #10 (1/2 inch), #12 (5/8 inch), all in a molded storage case.
The fixture can be bolted to a workbench (there are threaded holes in the base) or clamped in a vise. Removing the locking pin allows the fixture to open and change the dies that simply snap in place.
PAG oil is used in the A/C system for lubrication and is applied to the hose connections during assembly.
The fittings we used are the beadlock style. The ferrule is locked onto the tube; the crimping tool compresses it, which locks the hose in place.
Note the hole in the ferrule; it allows verification that the hose is bottomed in the fitting. This 90-degree A/C fitting includes a service port for charging the system.
With the proper dies in place the fitting is centered fore and aft in the fixture, which is closed and locked with a pin.
Tightening the screw in the top of the fixture with a ratchet squeezes the dies together. When the screw stops turning with light effort the crimp is secure.
If you find drill bits are spinning in your corded or cordless drill, remove the bit, saturate a rag with solvent, and clean the three internal chuck jaws. Over time cutting fluid, debris, and grease get in the chuck and allow the bits to slip. Also if you need to replace a chuck, the retaining screw is lefthand thread.
