COUPLING PLUG (JLG JL940010)

A damaged coupling plug can interrupt fluid or air flow in a connected line. This aftermarket replacement part references the JLG catalog number JL940010. The coupling plug serves as a connector that joins two sections of a hose or tube. Its plain mechanical function is to create a sealed joint that prevents leakage under pressure. A common failure consequence is that a worn plug may cause gradual pressure loss, reducing system effectiveness. During a routine check, a cracked or corroded coupling plug often requires immediate replacement to avoid further component strain. Verify the serial number or application, then call (562) 693-7748.
