This listing is for a Testo 557 digital HVAC manifold gauge set. The gauges are in good working condition, with no functional issues. The set includes three low-loss hoses, a vacuum hose, and a micron gauge that connects directly to the manifold. The original hanging hook is missing, but a replacement can be easily sourced online or from a parts house for a minimal cost.

This Testo 557 is ideal for HVAC professionals needing reliable digital readings for R410A systems. Despite the minor cosmetic flaw of the missing hook, the core functionality and included accessories make this a valuable tool.
