Industrial 26115R Closed System Constant Level Oiler

Trico 26115R #5 Closed System Constant Level Oiler automatically maintains a constant oil level in bearing housings and rotating equipment within industrial lubrication systems. With an 8 oz (240 mL) capacity, it uses a one-piece glass bottle with sight gauge and a 1/4 in. NPT connection, and it can mount from the side or bottom depending on the application. The unit operates as a pressure-balanced closed system, delivering oil to reduce moisture and contaminant ingress while sustaining a continuous supply for bearings at up to 250°F (120°C). It is designed for bearing lubrication and oil level control on rotating machinery such as pumps, gearboxes, electric motors, compressors, and steam turbines. Typical installations span power generation plants, oil and gas operations, chemical processing, paper mills, mining equipment, and general manufacturing facilities. In practice, maintenance teams and system integrators use the 26115R for constant level oiler replacements, lubrication system upgrades, preventive maintenance, and to improve equipment reliability. Related replacements include Trico 30205, 30210, and 30203.
