AC Hose Type C 5/16 Inch SAE J2064 for R134A Automotive Air Conditioning JUNZE

SAE J2064 Type C AC Hose from JUNZE is built around a simple idea: keep the refrigerant in and the contaminants out. The 5/16 inch hose uses a multi-layer construction with a nylon barrier layer that cuts refrigerant permeation significantly. We tested this against a standard non-barrier hose in a 500-hour R134A loop test. The JUNZE hose showed 87% less refrigerant loss. The synthetic rubber inner tube, textile reinforcement, and heat/oil/ozone resistant outer cover work together to handle the high-pressure discharge side of passenger car AC systems. Operating pressure is rated per SAE J2064. Full stop. That is the spec. For distributors, the value is in the consistent ID tolerance. Our bore variation stays within 0.13mm, which means your hose assemblies crimp the same way every time.
