Oil Level Indicator
The Oil Level Indicator (OLI) is a is a clear acrylic tube with 1/2” NPT threads at each end for lengths 3” to 15”. Red and green decals are included with the OLI to mark upper and lower limits, or to designate running oil level and idle oil level. It can be installed with the 1/2” ESBCAP optional breathers or if the user requires a closed loop, the 1/2” NPT can be used as a connector port to feed back into the system. See below for product details, specifications, temperature and pressure ratings and size and part number chart.
The Oil Level Indicator (OLI) was developed in response to the need of maintenance professionals to gauge the oil level inside large tanks, gearboxes and reservoirs. When water contamination is not a problem or when a regular Esco Oil Sight Glass is already installed at the drain port, the Oil Level Indicator can be utilized to monitor oil level. Made to replace the brass and glass sight gauges that stain and leak, the OLI is built to last.
