AC Line Repair Made Simple

AC Line Repair Kits

Our AC Line Repair Kits work for you at any line segment in the system. The standard kits have a compression style fitting and work much like a splice but with flexibility to it! These AC Line Repair Kits can also be ordered in custom lengths and with custom ends if needed.

Auto Cooling Solutions makes repairing or replacing your AC Lines easy, fast, and affordable.

Why Choose Flexible AC Hose?

Unlike rigid OEM lines, flexible AC barrier hose absorbs vibration, routes around obstacles, and makes installation far easier in tight engine bays or frame areas. Our hose is rated for high-pressure refrigerant systems and meets barrier hose standards to prevent refrigerant permeation.

AC Hose & Line Repair — Common Questions

Can you splice or repair a broken AC line?

Yes — our AC line repair kits are designed specifically for splicing a damaged section of AC hose or hard line. The compression fittings create a secure, leak-free connection without special tools.

What size AC hose do I need?

Most passenger vehicles use either #6 or #8 barrier hose for the high and low pressure sides. Check your OEM line diameter or contact us and we can try to help match the right kit.

Will these fit my vehicle?

Our rear AC line kits are vehicle-specific with direct-fit ends. The repair kits are universal and work on any AC line in the system. Use the fitment filters or reach out if you're unsure. If you only want a direct fit option you can use our Year Make and Model Search
