A nipple is a short, threaded hydraulic fitting used to join two fluid-carrying components — such as a hose, valve, or manifold port — within a machine's hydraulic system. It maintains a sealed, pressure-rated connection that allows hydraulic fluid to flow efficiently between the power source and the tool or drive unit. When a nipple is damaged, cross-threaded, or corroded, it can allow fluid to escape under pressure, causing a drop in system performance, potential contamination of surrounding components, and an unsafe operating condition. Replacing a worn fitting with the correct OEM part restores the hydraulic circuit to its original integrity.
