Description
The Yellow Jacket 49761 Compound Gauge is a 2-1/2" diameter low-side service gauge for R-410A HVAC systems. The compound gauge measures both pressure (0-500 PSI) and vacuum (-30" Hg to 0), providing the full measurement range needed for low-side HVAC service work. The R-410A refrigerant scale shows saturation temperatures corresponding to pressure readings, eliminating the need for separate temperature-pressure charts. The liquid-filled case dampens needle vibration for stable readings during system operation, and the stainless steel Bourdon tube provides accurate, long-lasting performance.
