OMTech 80W Laser Tube for CO2 Laser Engraver Borosilicate Glass Length 1250mm. No matter how well maintained, laser tubes-like light bulbs-are temporary parts that eventually burn out. Replace your old tube with Orion Motor Tech's heavy-duty 80W F4 laser tube.Made of tough borosilicate glass, this durable CO2 laser tube leaves competitors behind with its 8000-hour service life. Its beam can function as high as 95W, but at the cost of a shorter expected life. For engraving machines large enough to fit its 4' 1.2" (125 cm) length and 3.1" (8 cm) diameter, it installs quickly and easily: just solder the anode and cathode wires to your laser cutter and engraver machine's power supply and hook your water cooling system to the pipe fittings at either end. This CO2 laser tube is rated at 80W and can sustain beams as high as 95W for short periods of time, although this will shorten its 8000-hour service life; it operates at 18 kV and 26 kV or less. Installed in your laser machine, this tube's 4.5 mm (0.18)-diameter beam can work as an acrylic, cardboard, ceramic, cloth, glass, leather, paper, plastic, and wood engraver, cutter, and marker. The inner tube for the engraving laser beam is surrounded by a water pipe and hermetically-sealed outer tube to keep it cool and high functioning; ports at either end allow easy connection to your water reservoir and pump. This borosilicate glass laser tube is 1250 mm (4' 1.2") long and 80 mm (3.1") in diameter; your machine should have a little bit more space to allow proper fit. INSTALLS IN MINUTES, LASTS FOR YEARS.
