Sold without glass or rod, this fitting provides the top and bottom connection points required to mount a 5\/8-inch OD sight glass assembly. The bronze construction offers corrosion resistance suited to water service applications. Licensed plumbers and HVAC technicians install this fitting when servicing or retrofitting expansion tank gauge glass assemblies on closed-loop heating systems and pressure vessels.\u003c\/p\u003e\n\u003cp\u003eThis fitting is intended for expansion tank applications where a visual water level indicator is required. The top and bottom configuration allows the technician to establish a complete gauge glass run, connecting both ends of a 5\/8-inch OD glass tube to provide a direct reading of tank water level. It is commonly used in residential and light commercial hydronic heating systems where expansion tank monitoring is part of routine maintenance and system verification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-inch connection size fits standard expansion tank gauge ports\u003c\/li\u003e\n  \u003cli\u003eBronze construction provides corrosion resistance in water service\u003c\/li\u003e\n  \u003cli\u003eCompatible with 5\/8-inch OD sight glass tube\u003c\/li\u003e\n  \u003cli\u003eTop and bottom fitting set supports a complete gauge glass installation\u003c\/li\u003e\n  \u003cli\u003eSold without glass and rod, allowing use with separately sourced sight glass components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with expansion tanks requiring a 5\/8-inch OD gauge glass and 1\/2-inch top and bottom fitting connections.

Shut off system pressure and drain the tank or isolate the gauge port before removing or installing gauge fittings. Do not overtighten bronze fittings against glass tube ends, as this can crack the sight glass. Verify that the 5\/8-inch OD glass tube is sourced and cut to the correct length before completing the assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGlass Tube OD Compatibility\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Configuration\u003c\/strong\u003e: Top and bottom set\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGlass and Rod Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Expansion tanks\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: APOLLO VALVES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2070403\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"APOLLO VALVES","offers":[{"title":"Default Title","offer_id":51233845674290,"sku":"2070403","price":129.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307630105.jpg?v=1780110102","url":"https:\/\/voomisupply.com\/products\/apollo-valves-2070403-water-level-gauge-fitting-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
