1/8 in male needle valve type oil cup 50ML machine tool lathe mill sight gravity drip feed oiler lubricator This gravity drip feed oiler is designed to provide reliable lubrication for machine tools with a simple, maintenance friendly setup. It combines a 50 ml oil cup, a needle valve for precise drip control, and a sight to monitor oil level, all in a compact unit suitable for lathes and milling machines. Key benefits Precise lubrication: an adjustable needle valve lets you set the drip rate for consistent lubrication of tools, slides, ways, and matched components. Visual level indication: the sight feature provides an easy way to monitor oil level without disassembly. No external power required: gravity fed design operates without pumps or electricity, reducing setup complexity and energy use. Reduced waste and mess: controlled drip minimizes over oiling and oil splatter on work surfaces. Practical for machine tools: specifically aimed at lathes and mills, helping maintain smooth operation and extended component life. Easy to install and maintain: straightforward connection and simple refilling of the 50 ml cup keep downtime low. Key attributes Functionality: gravity drip feed oiler with a 1/8 inch male connection and adjustable needle valve for flow control. Compatibility: suitable for machine tools such as lathes and milling machines with compatible 1/8 inch male fittings. Capacity: oil cup holds 50 ml of lubricant between refills. Monitoring: built in sight feature to observe oil level at a glance. Performance: gravity driven lubrication with controllable drip rate for dependable oiling. Material: construction materials are not specified by the product listing. Size and fittings: 1/8 inch male thread connection; 50 ml cup capacity. Use cases Lathe lubrication during turning operations: attach the oiler to the machine's lubrication point to maintain spindle and feed screw lubrication with a controlled drip rate, reducing wear and seizing. Milling machine maintenance: install to supply a steady, visible flow of oil to ways, gears, and spindle bearings during cutting, helping maintain precision and reduce heat buildup. General workshop lubrication: use on small drills, grinders, or other machine tools that require gravity fed oil in a compact, easy to monitor oiler with a needle valve for drip adjustment.
