Trico 30010 16oz Glass 1/4in NPT Constant Level Oiler

The Trico 30010 is a new Opto-Matic constant level oiler featuring a No. 10 spherical clear glass reservoir with a 16 oz (oz) capacity and a chrome-plated zinc die-cast head assembly. The unit threads into equipment bearing housings via a 1/4 in NPT male fitting and maintains a consistent, preset oil level through a gravity-fed inverted-bottle mechanism — as oil drains into the bearing housing, atmospheric pressure allows only enough oil to flow to maintain the set level, preventing both over- and under-lubrication. The glass bowl construction allows direct visual inspection of oil level and condition without disassembly, and the chrome head incorporates an adjustable needle/feed screw for oil delivery rate control. Trico part number 30010 cross-references to Grainger item 6Y851 (visible on shipping label) and is compatible with standard Trico Opto-Matic mounting hardware; includes a chrome pipe fitting adapter and installation instruction sheet. Suitable for use on lathes, milling machines, grinders, motors, pumps, compressors, and other industrial machinery requiring continuous oil-bath lubrication.
