The custom a/c hose build page is to allow customers to purchase barrier hose by the inch with two fittings. The page will give us the information necessary to ship a hose that is crimped and ready to install. We use a bubble style crimper that allows us to guarantee the hose will not leak when using any automotive refrigerant. Please use the images to input the correct information when designing your custom hose. The webpage is setup to measure the hose by the inch, and add two fittings (one at each end) if you need an inline port you will have to call or email us to place the order. If you need rubber replaced that is attached to a hose manifold (two hoses with one fitting at one end ie: a compressor connection at one end and two separate connections at the condenser and evaporator) please email us a picture of the hose assembly for a price. If an aftermarket hose assembly is not available you can ship us the line to be rebuilt. We can quote the cost via email, please provide make, model, engine size, and year of the vehicle. We do not accept returns or exchanges on custom made hoses, please be sure your hose is correct prior to purchase. **PLEASE ENSURE YOUR ORDER ACCURACY BY SEARCHING THE PART NUMBERS BEFORE SELECTING FITTINGS ON THE CUSTOM HOSE PAGE***
