GLASS

618 035 29 GLASS A sight GLASS provides a direct visual indication of fluid levels within a system, such as a hydraulic reservoir or a lubrication tank. It's a simple yet essential component that allows operators and maintenance staff to quickly check if fluid levels are within the safe operating range without needing to open the system.

Typically found on the side of a hydraulic tank, a lubrication unit, or sometimes integrated into a control manifold, it plays a key role in preventing equipment damage. Without a clear view of fluid levels, a drill rig could run dry, leading to premature wear of pumps, motors, or drifter components. Maintaining correct fluid levels directly impacts the reliability of the drilling operation and helps avoid unexpected downtime.

Over time, the GLASS can become discolored, scratched, or cracked due to exposure to fluids, temperature changes, or physical impact. A cloudy sight GLASS makes it hard to accurately read levels, while a crack can lead to fluid leaks and contamination. If you notice any leaks around the sight GLASS or if the visibility is poor, it’s time for a replacement to maintain system integrity and ensure accurate monitoring.
