The bottom line: this compact 6.1 in sight glass combines clear fluid-level visibility with an integrated thermometer, making it a practical choice for maintenance technicians and equipment managers who need simultaneous level and temperature readings. The unit's polyamide construction, Buna-N O-ring seals and zinc-plated mounting hardware give confidence for commercial use, while the dual F\/C thermometer and 1\/2-13 threaded connection simplify installation and daily checks.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual measurement:\u003c\/strong\u003e The integrated thermometer displays temperature in both F and C alongside the sight glass so users can monitor level and temperature at once without extra gauges.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh visibility:\u003c\/strong\u003e A transparent polyamide sight window provides a wide, clear view of liquid level for quick visual confirmation during routine inspections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemical resistance:\u003c\/strong\u003e Ultrasonically welded polyamide construction and Buna-N O-rings resist common industrial fluids, preserving clarity in harsh environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard installation:\u003c\/strong\u003e Includes zinc-plated mounting bolts and a 1\/2-13 threaded connection with 5 in bolt spacing for secure, leak-proof attachment to standard tanks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal fluid compatibility:\u003c\/strong\u003e Specified compatible with hydraulic oil, mineral oil, petroleum-based and water-based fluids for broad shop and plant use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature rating:\u003c\/strong\u003e The thermometer is rated to 212F (100C), covering typical operating ranges for lubricants and hydraulic fluids.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe T-LLG-5 is suited for maintenance crews, hydraulic technicians and plant engineers who need a durable, low-maintenance sight gauge with temperature feedback built in.
