A plug cap is used to seal open ports, fittings, or fluid passages on equipment where a line, hose, or accessory is not connected. By closing off these openings, the cap prevents dirt, water, and foreign material from entering the system and causing damage to pumps, valves, or internal passages. When a plug cap is missing, cracked, or improperly seated, contamination can enter the fluid circuit or housing, leading to accelerated wear or component failure over time.
