Des-Case Oil Level Indicators & Accessories
Brands
Des-CaseThe Oil Level Indicator (OLI) was developed in response to the need of maintenance professionals to quickly gauge the condition and level of oil inside large tanks, gearboxes and reservoirs. The OLI is a clear high performance polyamide column with 1/2″ NPT threads at each end. Red and green level marker stickers are included with the 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.
* Stainless steel fittings and breather cap sold separately.
