AF-13455 Half Union for HVAC Systems

The JB Industries AF-13455 is a brass half union designed to connect refrigeration cylinders in HVAC service work. It provides a straight 0-degree joint between a 1/2 inch Acme male thread and a 1/4 inch SAE female thread. This fitting is built for technicians who need a reliable, permanent connection point on their manifold gauge sets or charging hoses.

Suits techs joining Acme to SAE flare

This union suits professionals adapting cylinder valves to standard quarter-inch flare fittings during evacuation or charging. It is not for installers needing a swivel nut for hose-end flexibility or a 45-degree elbow to clear tight service ports. Buyers requiring a full union to join two male threads or a different thread combination should look at other configurations.
