Manifold Gauge Sets

This category features professional-grade manifold gauge sets engineered for the diagnostic testing, evacuation, and charging of commercial, industrial, and institutional HVAC/R systems. The technical lineup includes precision 2-valve and high-flow 4-valve manifold configurations available in both analog flutter-free designs and advanced digital microprocessors with integrated Bluetooth connectivity. These diagnostic instruments feature heavy-duty forged brass, aluminum, or anodized block bodies equipped with optical sight glasses, double O-ring piston valves, and shock-absorbing protective rubber boots. Engineered to provide precise pressure and temperature drop readings across multiple refrigerant profiles—including high-pressure R-410A and modern low-GWP alternatives—these sets are paired with heavy-duty, high-pressure rated charging hoses featuring secure knurled fittings or low-loss ball valve couplers. This essential inventory provides certified HVAC/R technicians, mechanical contractors, and refrigeration engineers with the code-compliant, ruggedly built testing assets required to accurately analyze system performance, pull deep vacuums, and execute precise refrigerant charges.
