The 1pc 1/4' Male Needle Valve Type Oil Cup 200ML Machine Tool Lathe Mill Sight Gravity Drip Feed Oiler Lubricator is a compact lubrication device designed for machine tools. It uses a gravityfed oil cup with a builtin sight for level checking and a precision needle valve to control the drip rate, delivering a steady, metered flow to bearings and slides. Key benefits Precise lubrication: The needle valve allows fine adjustment of the drip rate for a consistent, controlled oil supply and reduced waste. Gravityfed design: No power source required; a selfcontained reservoir delivers lubricant directly to critical areas. Visible oil level: The sight feature lets you monitor remaining oil and refill before the reservoir runs dry. Reduced wear and downtime: Maintains a steady supply of lubricant to bearings, guides, and moving parts, helping extend tool life. Easy installation: 1/4' male thread enables straightforward mounting and compatibility with standard ports. Large capacity: 200 ml reservoir minimizes frequent refills during longer operations. Key attributes Function: Gravity drip feed oiler lubricator with oil cup Capacity: 200 ml Connection: 1/4' male needle valve Type: Oil cup Sight: yes, for level monitoring Applications: suitable for machine tools such as lathes and mills Material: not specified Performance: adjustable drip rate for controlled lubrication Applications and use cases Lathe operations: Install on a metal lathe to provide a steady drip of lubricant to spindle bearings during long turning runs, helping reduce friction and wear. Milling operations: Mount on a milling machine to lubricate ways and cutters, improving part finish and extending tool life. Retrofit and maintenance: Add to older machines that rely on manual oiling, providing a visible oil level and controlled gravityfed lubrication without additional power sources. Usage and maintenance tips Mount the oiler on a suitable location with a compatible 1/4' male thread port. Fill the oil cup with the appropriate lubricant for your equipment and check viscosity compatibility. Use the needle valve to set a slow, steady drip rate that meets the machine's lubrication needs. Regularly inspect the sight level and refill before the reservoir is empty. Check fittings for leaks and keep the oil path clean to ensure consistent flow.
