Custom A/C Hardlines Video Instructions:

So you ordered up a Sure Fit A/C kit from Vintage Air that was, as its name implies, sure to fit your application. What you didn’t remember were those “minor” modifications like aftermarket inner fenders and/or core support you installed. Oops! Now all those pre-bend refrigerant hardlines that were made to work with your vehicle (if it were stock) don’t quite work. But, you’re in luck because Vintage Air will gladly make custom A/C hardlines specifically for your application. This little tech tip will show you how.

To give you some context, we were trying to finish up the Vintage Air A/C install on our 1967 Nova Week To Wicked project when we came across the situation above. Non-stock parts that meant stock hardlines wouldn’t work. We called up Vintage Air to see what our options were. We were pleased to hear that they can make custom A/C hardlines, we just needed to send them a template.

Making an accurate template is pretty darn easy, there are just a few parameters you’ll need to know before you do the same for your project. A coat hanger or welding wire is all you need to mock-up the correct bends and give Vintage Air a template to work off of. We’ll go over those steps below.

How To Make A Template For Custom A/C Hardlines

start your template for the custom A/C hardlines from where the O-ring bottoms out
Your template should start from where the O-ring bottoms out in the fitting.
Leave sufficient space from the flair end for the custom A/C hardlines
Then measure outward and mark your first bend. Leave sufficient space from the flair end to the first bend. See table for minimum measurements.
Use a piece of pip to make an accurate bend for the hardlines
Use a piece of pipe sized correctly for number hardline to make an accurate bend. Again, see table for what diameter to use per each size of hardline.
mark where you want your bend to end for the custom A/C hardlines
Then, continue to form the wire in your desired path. Make sure to mark where you want your bend to end when lining up and marking your wire.
note your desired flare for each end and the size to be used
Once you’ve created an accurate pattern you are satisfied with, it is time to label it. Use painters tape or similar to note your desired flare (male or female) for each end and the size hardline to be used.
This is how the custom A/C hardlines turned out
We sent off two patterns to have hardlines made from the condenser through the core support. This is how they turned out!
