BULKHEAD

BG 004 386 86B BULKHEAD This fitting acts as a fixed, sealed pass-through for hydraulic hoses, typically mounted on a machine frame, a control cabinet wall, or a component housing. Its main job is to provide a stable anchor point for hose connections, preventing them from chafing against sharp metal edges and protecting them from excessive movement and vibration during operation. By creating a secure transition point, it maintains the integrity of the hydraulic circuit.

A failure in a BULKHEAD fitting can lead to significant problems. Even a small hydraulic leak at this point can reduce the pressure available for critical functions like percussion or rotation, slowing down your entire drilling cycle. More seriously, a complete failure can result in a high-pressure oil spray, which is a major safety hazard, and can cause unexpected movement of the boom or feed system. Maintaining a leak-free system starts with solid connection points like this one.

Look for signs of weeping oil or physical damage around the fitting's base and threads during your daily walk-arounds. If a leak is present, simply over-tightening an old fitting is often not a lasting solution. For a dependable repair, it's best to replace the BULKHEAD fitting entirely. Remember to always release any stored pressure in the hydraulic system before attempting to loosen or remove any fittings.
