What the AI looks for in Automotive Replacement Air Conditioning Hoses
- Barrier hose
- Use nylon-lined barrier hose for R-134a and R-1234yf Non-barrier hose allows refrigerant to permeate and the system slowly loses charge.
- Size
- #6 is 5/16 in ID, #8 is 13/32 in, #10 is 1/2 in, #12 is 5/8 in The size must match the fittings and the system's flow needs.
- Standard or reduced wall
- Match the wall type to your fittings and crimp dies Reduced-wall hose takes different fittings than standard hose.
- Bulk vs assembly
- Buy bulk hose only if you have a proper A/C crimper; otherwise buy a finished assembly Hand-made joints without a correct crimp leak.
Brands that matter
- Gates: A/C barrier hose.
- Four Seasons: Bulk hose and assemblies.
- Santech: Hose with matching fittings.
- Mastercool: Hose sized to its crimping system.
What to avoid
- Fuel, heater or hydraulic hose used in place of A/C hose
