It monitors both system pressure and fluid temperature simultaneously, giving technicians a quick visual read of operating conditions at a single port. The pressure range runs from 0 to 75 psi and the temperature scale covers 50 to 320 degrees F. The gauge threads into a standard 1\/2 inch NPT fitting, making installation straightforward on most domestic hot water and hydronic system configurations. Licensed plumbers and HVAC technicians are the primary installers of this type of gauge during new equipment startup or service replacement.\u003c\/p\u003e\n\u003cp\u003eThis gauge is suited for residential and light commercial hydronic heating systems and water heating equipment where a single instrument must display both pressure and temperature readings. It is typically mounted on the system supply side near the heat exchanger or storage vessel. Applications include boiler systems, indirect water heaters, and similar closed-loop hydronic equipment where continuous monitoring of operating parameters is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCombination gauge reads both temperature and pressure from a single 1\/2 inch NPT port\u003c\/li\u003e\n  \u003cli\u003ePressure range of 0 to 75 psi covers typical residential and light commercial hydronic system operating conditions\u003c\/li\u003e\n  \u003cli\u003eTemperature scale of 50 to 320 degrees F accommodates standard hot water and low-temperature hydronic systems\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch NPT threaded connection fits common boiler and water heater tapping configurations\u003c\/li\u003e\n  \u003cli\u003eOEM replacement part sourced directly from LOCHINVAR for accurate fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement temperature and pressure gauge for LOCHINVAR water heating and hydronic boiler equipment requiring a 1\/2 inch NPT combination gauge with a 0 to 75 psi pressure range and a 50 to 320 degrees F temperature range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified HVAC technician. Before removing the existing gauge, shut off the heat source, relieve system pressure, and allow the system fluid to cool to a safe handling temperature. Apply suitable thread sealant to the NPT threads per local plumbing code requirements before threading the gauge into the tapping. Do not overtighten the gauge body, as excessive force can crack the gauge case or distort the fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0-75 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: 50-320 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1\/2 inch NPT\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: LOCHINVAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: L100208153\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOCHINVAR","offers":[{"title":"Default Title","offer_id":51348036387122,"sku":"L100208153","price":114.89,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552808.png?v=1782118803","url":"https:\/\/voomisupply.com\/products\/lochinvar-l100208153-temperature-pressure-gauge","provider":"Voomi Supply","version":"1.0","type":"link"}
