The Yellow Jacket 42041 2-Valve Heat Pump Manifold includes both high and low-side gauges with steel casing and polycarbonate crystal which can handle up to 800 psi to read heat pump pressures and transitions in heating or cooling mode. The 1 percent accuracy of the gauges provide the user with the level of accuracy needed for critical charge systems. With the color-coded scales, the user can easily read the larger dials.

The forged brass body is durable for a longer service life while the double O-ring piston design reduces wear. The nylon seats are long-lasting and the metal valve handles allows for easy operation. The full porting maximizes capacity and flow.
