This 1pc 1/4' Male Needle Valve Type Oil Cup 50ML is a gravity fed oiler lubricator designed for machine tools such as lathes and mills. It combines a needle valve for precise drip control with a compact 50ML oil cup and a sight friendly design for easy monitoring of oil level. The 1/4' male connection supports common mounting and fitting configurations found on machine tool lubrication systems. Key benefits Precise drip control: The needle valve enables fine adjustment of the oil flow, helping to apply lubrication exactly where it is needed and minimizing waste. Simple gravity feed: Uses gravity to deliver lubricant at a steady rate without requiring pumps or complex plumbing, reducing maintenance and potential failure points. Easy level monitoring: Sight capable design allows quick visual checks of oil level to prevent running dry during operation. Reduced refills with 50ML capacity: The compact cup holds a substantial amount of oil for extended use between refills in typical workshop setups. Broad compatibility: 1/4' male connection matches standard fittings and mounting configurations on machine tools and lubrication lines.
