Product Summary: Yellow Jacket 42006 Series 41 Manifold
The Yellow Jacket 42006 is another staple in the Series 41 "Test and Charging" line. While it shares the same heavy-duty chassis as the 42004, it is calibrated for a different set of common refrigerants, making it the preferred choice for technicians working on older residential systems and medium-temperature commercial refrigeration.
Key Features
Expanded Refrigerant Profile: Specifically calibrated for R-22, R-134a, and R-404A.
High-Accuracy Gauges: Includes large 3-1/8" (80mm) color-coded gauges with 1% accuracy (Class 1), essential for critical charge systems.
Full Kit Included: Unlike the 42004 (which is often sold as a block-only unit), the 42006 typically comes as a complete set including three 60" PLUS II™ hoses with standard 1/4" flare fittings.
Rugged Build: Features a forged brass body, a steel gauge case, and polycarbonate crystals for impact resistance.
Proven Internal Design: Uses a sliding double "O" ring piston and long-life nylon seats to ensure a leak-proof seal even after years of use.

42004 vs. 42006: What's the Difference?
The primary difference is the refrigerant compatibility:
42004: Includes R-410A (Modern high-pressure AC).
42006: Swaps R-410A for R-134a (Automotive and commercial refrigeration).
