CONNECTION R

CONNECTION R 8440 3601 03 Functioning as a critical link in a hydraulic or pneumatic circuit, this connection fitting ensures that fluid power is transmitted without loss. It joins lines together, often in tight spaces around the drifter, feed beam, or power pack. A proper seal at this point is essential for maintaining system pressure and directing hydraulic oil or compressed air exactly where it's needed for the machine to operate correctly.

Even a small leak from a faulty connection can have significant consequences. It can lead to a gradual loss of hydraulic fluid, causing pumps to run dry and overheat. A sudden failure can release a high-pressure stream of oil, creating a serious safety hazard and reducing drilling performance due to lost pressure in the percussion or rotation circuits.

Look for signs of weeping or dripping oil around the fitting as an early indicator of failure. Before attempting any work, always ensure the hydraulic system is completely depressurized. When installing a new connection, verify that the threads are clean and undamaged to prevent cross-threading, which will ruin both parts and fail to create a proper seal.
