Male Tube-O, 45 Deg EL

Description & Features

Designed for use with R134a and R12 refrigerant systems, this carbon steel Male Tube-O, 45 Deg EL fitting is well suited to heavy-duty truck, industrial, and automotive applications where reliable tube-to-hose connections are required. The 45-degree elbow geometry accommodates routed assemblies where straight fittings would not fit without excessive bending stress on the hose.

Manufactured under the Aeroquip brand, the fitting features Dura-Kote plating for corrosion resistance in demanding service environments. The ORB (O-ring boss) male end pairs with a -12 hose dash size on the line/hose/tube end, with an end size of 0.875 inches and a drop dimension of 1.19 inches. The system-engineered design supports extended hose assembly service life and maximum uptime in high-cycle applications.
