It features a 1\/2-20 UNF thread connection and a sight length of 3-9\/32 inches, making it suitable for compact installation spaces. Rated to 125 psi maximum working pressure and a maximum temperature of 225 degrees F with a 70-degree F working temperature rating, this gauge uses a Buna-N seal for fluid compatibility. The overall length from center of base is 5 inches. Plumbers, pipefitters, and industrial maintenance technicians install this gauge where continuous level monitoring of closed-loop fluid systems is required.\u003c\/p\u003e\u003cp\u003eThe G613-05-A-1 is suited for use in closed circuit hydraulic, lubrication, coolant, and fluid reservoir applications where visual level confirmation is needed under pressure. The rigid plastic body keeps weight low while the aluminum housing provides structural support at the mounting base. It is appropriate for both light industrial and mechanical system environments where fluid level must be verified without draining or opening the system. The Buna-N seal supports compatibility with a range of common petroleum-based and water-based fluids.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClosed circuit design allows fluid level monitoring without interrupting system pressure\u003c\/li\u003e\n\u003cli\u003e1\/2-20 UNF thread for direct installation into standard tapped ports\u003c\/li\u003e\n\u003cli\u003e125 psi maximum pressure rating suits pressurized reservoir and hydraulic applications\u003c\/li\u003e\n\u003cli\u003eBuna-N seal provides resistance to common petroleum-based and water-based fluids\u003c\/li\u003e\n\u003cli\u003eRigid plastic sight window with aluminum housing base for durability and weight savings\u003c\/li\u003e\n\u003cli\u003eMaximum temperature rating of 225 degrees F covers most standard fluid system operating ranges\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-install sight gauge for closed circuit fluid systems with 1\/2-20 UNF threaded ports rated within the 125 psi and 225 degrees F operating limits of this gauge.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified plumber, pipefitter, or maintenance technician. Depressurize and drain the system before removing any existing sight gauge or fitting. Ensure the port thread is clean and undamaged before installing; use appropriate thread sealant compatible with the system fluid. Do not overtighten the housing into the port, as the rigid plastic sight body can crack under excessive torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: 1\/2-20 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSight Length\u003c\/strong\u003e: 3-9\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length to Center of Base\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pressure\u003c\/strong\u003e: 125 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 225 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Temperature\u003c\/strong\u003e: 70 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Buna-N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Rigid Plastic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LDI INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: G613-05-A-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LDI INDUSTRIES","offers":[{"title":"Default Title","offer_id":67912207270194,"sku":"G613-05-A-1","price":64.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/081f9942fdfe6b8fd168b7c4c2bc29af.jpg?v=1791229839","url":"https:\/\/voomisupply.com\/products\/ldi-industries-g613-05-a-1-liquid-level-sight-gauge","provider":"Voomi Supply","version":"1.0","type":"link"}
