Heat pumps use the same refrigeration cycle for heating and cooling. A heat pump can change which coil is the condenser and which is the evaporator by way of a reversing valve. Using a traditional manifold to service a heat pump is not advisable as the los side of the gauge will be damaged when the system goes into heating mode. Therefore, both gauges of the manifold must be designed to handle the high pressures of the heating mode. The GemTech heat pump manifold Made in the USA has two 3-1/8" glow-in-the-dark Class One 1% accuracy gauges designed with 800 psi to handle the heat pump pressures. Because of the significant temperature glide on R-407C, the pressure/temperature scale is based on saturated vapor (dew point DP). For temperatures above 50 degrees, the scale is based on saturated liquid (bubble point BP). Use the DP for superheat calculations and the BP for subcooling calculations
  • Two class one 1% accuracy glow-in-the-dark metal gauges designed for 800 psi heat pump pressures
  • Replaceable intake hose and holder fittings
  • Classic forged brass body

Please Note! The actual brand name on product received may vary from the description but will always be manufactured to the same strict standard of quality.
