SEAL - COPPER (Komatsu KO3KA-21-11670)

A damaged copper seal can allow fluid or gas to escape from a sealed joint, leading to system inefficiency or contamination. During assembly, a copper seal compresses to fill surface irregularities and create a leak-resistant barrier. The catalog reference for this aftermarket replacement part is Komatsu part number KO3KA-21-11670. Copper seals are commonly used in high-temperature or high-pressure connections where softer gaskets would fail. A failed seal may cause gradual loss of pressure or fluid, resulting in reduced performance or component wear. Keeping a copper seal in sound condition helps maintain proper sealing force over repeated thermal cycles. Verify the serial number or application, then call (562) 693-7748. This item ships at approximately 0.006 pounds.
