The boot slips over the outer housing of a compatible gauge face, providing a protective rubber or vinyl collar that shields the gauge from impact, abrasion, and jobsite handling. Licensed HVAC technicians and refrigeration service professionals install these boots as part of routine manifold gauge maintenance or when an existing boot becomes cracked, torn, or missing. The red color follows the standard industry convention for the high-side gauge position on a refrigerant manifold set.\u003c\/p\u003e\n\u003cp\u003eThis gauge boot is suited for use with 3.125-inch manifold gauges commonly found in residential and light commercial HVAC and refrigeration service manifold sets. It is a straightforward replacement accessory that restores the protective collar on a worn or damaged gauge without requiring replacement of the full gauge or manifold assembly. YELLOW JACKET manifold gauge sets are widely used by HVAC-R service professionals across residential, commercial, and refrigeration applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRed color designates high-side gauge position per standard HVAC-R service convention\u003c\/li\u003e\n  \u003cli\u003eDesigned to fit 3.125-inch diameter manifold gauge housings\u003c\/li\u003e\n  \u003cli\u003eProtective boot shields gauge face from impact and abrasion during field use\u003c\/li\u003e\n  \u003cli\u003eReplacement accessory extends the service life of existing manifold gauges\u003c\/li\u003e\n  \u003cli\u003eSlip-on installation requires no special tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement gauge boot for 3.125-inch diameter HVAC-R manifold gauges.

Ensure the gauge housing is clean and free of debris before seating the boot to achieve a snug fit. No tools are required for standard slip-on boot installation. Inspect the gauge itself for calibration accuracy whenever performing gauge set maintenance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge Boot Diameter\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Red\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: 49191\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YELLOW JACKET","offers":[{"title":"Default Title","offer_id":51468643041586,"sku":"49191","price":24.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/49191.gif?v=1783919621","url":"https:\/\/voomisupply.com\/products\/yellow-jacket-49191-red-gauge-boot-3-125-in","provider":"Voomi Supply","version":"1.0","type":"link"}
