Standard Barrier A/C Hose

Designed with a thicker inner barrier layer (typically nylon), standard barrier hose provides excellent resistance to refrigerant permeation—especially critical for systems using R-134a. It’s highly durable and well-suited for heavy-duty or high-vibration applications, but comes with a larger outside diameter (OD) and reduced flexibility, which can make routing in tight spaces more challenging.

Kurt Hydraulics AC fittings and hoses are validated to SAE J2064.
