Grease nipples, also known as lubrication fittings or grease fittings, are small but essential components used to deliver lubricant (grease) into bearings, bushings, and other moving parts of machinery. They act as a one-way valve, allowing a grease gun to inject lubricant while preventing dirt and contaminants from entering. Available in various configurations—including straight, 45°, and 90° angled types—they provide access in tight or hard-to-reach areas.
