AC Hose by the Foot or Spool | Barrier & Reduced-Barrier Hose | No Minimum Order

Standard barrier hose has a thicker wall with a full HNBR barrier layer — stiffer and easier to route in open spaces, correct for high-side discharge lines. Reduced barrier hose has a thinner barrier layer making it smaller in diameter and more flexible, ideal for tight chassis routing or anywhere standard hose would kink. Both carry the same pressure rating and both meet SAE J2064 standards.

Yes. All our bulk AC hose meets SAE J2064 standards and is compatible with both R134a and R1234yf refrigerant systems. If your vehicle uses R1234yf (most 2015 and newer models), this hose is the correct specification.

To cut raw hose you need a sharp blade or hose cutter — a clean straight cut matters for a good seal. To attach fittings, it depends on the fitting type: crimped hose ends require a hydraulic or pneumatic crimping machine (typically done at a shop). If you want a no-crimp repair option, our EZ Flex Repair Kits use compression aluminum fittings that tighten with a standard wrench — no crimper needed.

Measure the inside diameter of your existing AC hose or the outside diameter of the fitting it connects to. AC hose sizing follows the SAE # system: #6 = 5/16", #8 = 13/32", #10 = 1/2", #12 = 5/8", #14 = 3/4". When in doubt, the high-side (smaller, liquid line) is typically #6 or #8, and the low-side (larger, suction line) is typically #10 or #12 on most trucks and SUVs.

Yes, however for rear AC hose replacement on specific domestic US vehicles we recommend our direct-fit Rear AC Line Sets — they're a complete rear AC line assembly with the correct fittings, o-rings, and hardware for your exact vehicle. Bulk AC hose is best when you need a custom length and you're building custom AC lines.
