It features 3.125-inch color-coded gauges housed in rugged steel cases with polycarbonate crystals, delivering 1% accuracy (Class 1) for precise readings during charging, recovery, and evacuation procedures. Dual-scale readout displays both bar and psi, as well as Fahrenheit and Celsius, making it versatile for service work across a range of job-site conditions. HVAC technicians rely on this type of manifold for critical charge work where gauge accuracy directly affects system performance and refrigerant compliance.\u003c\/p\u003e\n\u003cp\u003eThe 42021 is suited for residential and light commercial HVAC service involving R-32 and R-410A refrigerants. These refrigerants operate at higher pressures than legacy refrigerants, making the Class 1 accuracy rating and durable steel case construction especially relevant for technicians performing precise charge measurements on modern split systems, mini-splits, and heat pumps. The large-diameter gauges improve readability in field conditions, reducing misread errors during charging operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3.125-inch color-coded gauges for improved field readability\u003c\/li\u003e\n  \u003cli\u003e1% accuracy (Class 1) for critical refrigerant charge applications\u003c\/li\u003e\n  \u003cli\u003eRugged steel gauge cases with polycarbonate crystals for durability\u003c\/li\u003e\n  \u003cli\u003eDual-scale display: bar and psi, Fahrenheit and Celsius\u003c\/li\u003e\n  \u003cli\u003eCompatible with R-32 and R-410A refrigerants\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with R-32 and R-410A refrigerant systems as stated by the manufacturer.

Always recover refrigerant before opening a system to atmosphere and confirm all connections are properly seated and leak-free before opening manifold valves. Do not use this manifold with refrigerants other than those for which it is rated, as cross-contamination and pressure mismatch can cause equipment damage or personal injury.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Refrigerants\u003c\/strong\u003e: R-32, R-410A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge Diameter\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 1% (Class 1)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Scale\u003c\/strong\u003e: bar and psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Scale\u003c\/strong\u003e: degrees F and degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrystal Material\u003c\/strong\u003e: Polycarbonate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: YELLOW JACKET\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 42021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YELLOW JACKET","offers":[{"title":"Default Title","offer_id":51467385143602,"sku":"42021","price":115.89,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313948466.jpg?v=1783903069","url":"https:\/\/voomisupply.com\/products\/yellow-jacket-42021-series-41-r-32-r-410a-manifold-set","provider":"Voomi Supply","version":"1.0","type":"link"}
