AC Hose Type E 13mm ID SAE J2064 R134A Heavy Duty AC Hose JUNZE

JUNZE Type E AC Hose in 13mm ID is built for the suction side of systems that demand higher refrigerant flow. The 13mm bore delivers roughly 28% more cross-sectional area than an 11.5mm hose, which means less restriction on the return side. Rated for 3.5MPa working pressure with minimum burst pressure of 18.0MPa (A series). Operating temperature from -40°C to +135°C. The 4-layer construction is the same across all our Type E sizes — nylon barrier, synthetic rubber tube, textile reinforcement, heat/ozone resistant outer cover. That consistency matters because it means your crimping parameters stay the same regardless of which diameter you are working with. Same hose construction, different bore size. That is it. We visited an AC assembly plant in India that was using three different hose constructions for three different diameters. They standardized on our Type E across all sizes and reduced their crimp setup time by 40%.
