Measuring 3\/4 inch outer diameter and 24 inches in length, this gauge glass installs in the sight glass fitting of a boiler to allow operators and technicians to monitor water level at a glance. The red line stripe running the length of the tube enhances visibility, making it easier to read the water level under varying light conditions. Boiler technicians and licensed plumbers typically handle installation and replacement of gauge glass assemblies as part of routine boiler service.\u003c\/p\u003e\u003cp\u003eThis gauge glass is suited for use in residential and light commercial boiler applications where a 3\/4 inch OD sight glass fitting is specified. It is commonly found on hot water and steam boilers and serves as a direct replacement during scheduled maintenance or when the existing glass has become etched, clouded, or cracked. The 24 inch length accommodates standard boiler gauge glass column configurations requiring that tube length.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRed line stripe for improved water level visibility\u003c\/li\u003e\n\u003cli\u003e3\/4 inch outer diameter fits standard boiler sight glass fittings of that size\u003c\/li\u003e\n\u003cli\u003e24 inch length suits common boiler gauge column configurations\u003c\/li\u003e\n\u003cli\u003eDesigned as a replacement tube for boiler liquid level gauge assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement gauge glass for boilers and steam systems equipped with 3\/4 inch OD sight glass fittings requiring a 24 inch tube.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGauge glass replacement should be performed by a licensed boiler technician or plumber in accordance with local boiler codes and the boiler manufacturer's service procedures. Always shut down the boiler, isolate the gauge glass valves, and allow the system to depressurize and cool completely before removing the old glass. Handle glass tubes carefully to avoid stress fractures, and inspect packing, washers, and fittings for wear before installing the new tube. Follow all applicable local and national boiler safety codes when performing service on pressurized systems.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 24 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Red Line Gauge Glass\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CROWN ENGINEERING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 34rl24\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CROWN ENGINEERING","offers":[{"title":"Default Title","offer_id":51468219908402,"sku":"34RL24","price":69.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945360.png?v=1783914848","url":"https:\/\/voomisupply.com\/products\/crown-engineering-34rl24-red-line-gauge-glass","provider":"Voomi Supply","version":"1.0","type":"link"}
