This oil cup is a gravity fed lubrication solution designed for machine tools. It features a 1/8 inch male needle valve for precise flow control, a 16 ml capacity oil cup, and a sight window to monitor the oil level. The gravity drip feed design provides a simple, reliable oil supply to the target area without pumps or power. Key features and benefits Precise flow control: 1/8 inch male needle valve allows fine adjustment of the drip rate for accurate lubrication. Visible oil level: sight window enables quick, ataglance monitoring of remaining oil. Adequate capacity: 16 ml oil cup size suited for short runs and intermittent lubrication needs. Gravity fed operation: no external power or pumps required, reducing complexity and maintenance. Suitable for machine tools: designed for use with lathes and milling machines to lubricate critical moving surfaces. Reliable connection: 1/8 inch male threaded interface for easy mounting and compatibility with common lubrication setups. Key attributes Functionality: gravity drip feed oiler lubricator with needle valve for adjustable flow. Compatibility: appropriate for machine tools such as lathes and mills that use a 1/8 inch male connection. Size: oil cup capacity of 16 ml; compact form for tight spaces. Material: not specified in the product description. Performance: gravityfed design provides steady lubrication delivery with adjustable flow via the needle valve and a sighted oil level. Two to three use cases Lathe spindle lubrication: Attach to the lathe to provide a controlled drip of oil to spindle bearings, helping reduce wear and keep the bearing surfaces properly lubricated during operation. Milling machine ways and leadscrews: Install near the leadscrew or ways to deliver a steady drip of lubricant, promoting smooth movement and reducing resistance during milling tasks. General workshop lubrication: Use on other small to midsize machine tools or sliding components that benefit from visible, gravityfed oil delivery without the need for electrical pumps or complex plumbing. Applications For machine tools requiring a gravity drip feed oiler with a sight to monitor oil level. Ideal where a user needs adjustable drip rate to match a specific lubrication requirement. Suitable for setups with a 1/8 inch male threaded connection.
