CONNECTING NUT

314 270 18 CONNECTION NUT This T-fitting serves as a crucial connection point within the hydraulic or pneumatic systems of a rock drill. Its primary job is to split a single fluid line into two separate paths or to combine two lines into one. You will typically find these connectors in various locations, such as within the main valve block, along the boom's hydraulic lines, or in the drifter's air or water flushing circuits.

The integrity of this fitting is essential for consistent drilling performance and operational safety. Even a small crack or a damaged thread can cause a significant loss of hydraulic pressure, which might slow down the drifter's rotation or weaken the feed force. A sudden failure can also create a dangerous high-pressure oil spray, posing a risk to personnel and the environment.

Look for signs of wear like visible fluid leaks, weeping around the threads, or physical cracks in the fitting body. A hissing sound often indicates a compressed air leak. When replacing this part, always ensure the system is de-pressurized. Clean the connection points thoroughly and check that the threads on the hoses or pipes are in good condition to ensure a proper seal.
