Yellow Jacket 42004 Series 41 Manifold R-22 R-404A R-410A

Product Description

The YELLOW JACKET 42004 Series 41 Manifold is a brass-body charging manifold designed for refrigerant service work on systems charged with R-22, R-404A, or R-410A. It ships as a complete assembly, including 60-inch Plus II hoses with standard 1/4-inch flare fittings and large 3-1/8-inch gauges for clear pressure readings in the field. The large, easy-grip handles allow precise valve control during recovery, evacuation, and charging procedures. Built for HVAC technicians who need a reliable, readable manifold on residential and light commercial refrigeration and air conditioning equipment.

The 42004 is suited for residential and light commercial HVAC and refrigeration service. Its compatibility with three common refrigerants - R-22, R-404A, and R-410A - makes it a practical choice for technicians servicing mixed fleets of older R-22 equipment and newer HFC systems. The included 60-inch hoses provide adequate reach when working around condensing units and evaporator coils without the need to purchase hoses separately.

Ensure hose connections are hand-tight and leak-free before opening any valves. Do not mix refrigerants or use this manifold on systems charged with refrigerants not listed in the compatibility section.
