Needle Valve Gravity Drip Feed Oiler with Sight Glass automatic lubrication machine oil cup 100ml G1/4

["Needle valve oiling cups can precisely control the amount of lubricant dripping by adjusting the opening of the needle valve to ensure that the lubrication point gets the right amount of lubricant.","Equipped with a transparent window (Sight Glass), you can visually observe the oil level in the oil cup, making it easy to replenish the lubricant in time.","Adopting the gravity drip principle, the lubricant is adjusted through the needle valve and naturally drips down to the lubrication point by gravity, without external power.","Easy to install and remove, operators can easily refill lubricants or replace parts.","Crafted from chrome-plated carbon steel, this oil cup is highly corrosion-resistant and rust-proof, making it an ideal replacement for your old unit."]
