Yellow Jacket 42044 Heat Pump Manifold with 60″ hoses,3-1/8″, 1 percent accuracy high- and low-side gauges that both handle up to 800 psi to read heat pump pressures and transitions in heating or cooling mode.

The Yellow Jacket Heat Pump Manifold features two 800 psi gauges to read all heat pump pressure conditions. Traditional low side manifold gauges can be susceptible to damage when heat pumps go into heating mode. Because the low side gauge of the Yellow Jacket Heat Pump Manifold is also designed for pressures up to 800 psi, it can read the pressure whether the pump is in heating mode, cooling mode or transition.

Both black steel case gauges are 3-1/8 inch with 1 percent accuracy full scale. The heat pump manifold temperature scales cover the three most common refrigerants used in heat pumps: R-22, R-410A and R-407C. Made in USA.
