PLUG - EXPANSION (Linde LI11021F5400)

A damaged expansion plug can allow coolant or fluid to leak from a sealed passage. During inspection, an expansion plug may show signs of corrosion or deformation that compromise its seal. Keeping an expansion plug in sound condition helps prevent sudden fluid loss and potential overheating. This aftermarket replacement part references Linde as the OE maker and carries the cross-reference number LI11021F5400. The plug functions as a mechanical seal that closes core holes in cast components. A common failure consequence is a slow drip that escalates into a pressurized leak under operating temperatures. Verify the serial number or application, then call (562) 693-7748.
