CAP37 DEG F

CAP37 DEG F 2695 2573 25 Used throughout a drilling rig's hydraulic circuits, this cap provides a positive seal on any open 37-degree male flare fitting. Its main job is to keep hydraulic oil in and contaminants out. You will find these caps on unused ports of valve blocks, disconnected hose ends during service, or on diagnostic test points. By preventing dirt and water from entering the system, it plays a key role in protecting high-precision components like pumps, control valves, and the drifter.

A missing or improperly tightened cap can lead to more than just a messy oil leak. A constant drip creates a serious slip hazard for personnel and a potential fire risk. More importantly, leaving a port open to the mine environment allows abrasive dust and moisture to enter the hydraulic fluid. This contamination is a primary cause of premature wear and sudden failure in the entire hydraulic system, which can stop a drill in its tracks.

Check for leaks around capped ports during routine inspections. If you see weeping or dripping, the cap may be loose or its sealing surface damaged. When installing, always ensure the threads and the flare cone are clean. Tighten the cap firmly but do not overtighten, as this can damage the fitting. Always replace a cap if it shows any signs of corrosion, cracked threads, or physical damage.
