What the AI looks for in Automotive Replacement Air Conditioning Fittings
- Hose size
- Barrier hose sizes: #6 is 5/16 in ID, #8 is 13/32 in, #10 is 1/2 in, #12 is 5/8 in The fitting must match the hose ID exactly for a sound crimp.
- Crimp style
- Match the fitting to the hose type (standard or reduced-wall barrier) and to your crimper's dies (beadlock or standard) A fitting crimped with the wrong die or on the wrong hose leaks or blows off.
- Connection type
- Identify the mating end: male or female O-ring, flare, spring-lock or manifold block These types are not interchangeable.
- Refrigerant compatibility
- Use fittings and barrier hose rated for R-134a or R-1234yf, not old R-12 rubber hose Non-barrier hose leaks R-134a through its walls.

What to avoid
