Manifold gauge sets—also called HVAC gauges or refrigeration gauges—are frequently used to diagnose and repair cooling or refrigeration systems. They measure low- and high-refrigerant pressure using mechanical or digital gauges to identify issues like leaks or to help with system evacuation and recharge.

Professionals wishing to vacuum, diagnose, charge, or evacuate the refrigerant in vehicle air conditioning systems can use our high-quality manifold gauge and hose set.
