Monitor the oil level in your machine with DES-CASE Oil Level Indicators. The DES-CASE 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. The DES-CASE OLI is a clear acrylic column with 1/2" NPT threads at each end. Red and green level marker stickers are included with the DES-CASE OLI to mark upper and lower limits, or to designate running oil level and idle oil level. Utilizing the drain port, operators can visually monitor the fluid level within reservoirs.
