SEAL (JLG JL91474478)

JL91474478: A worn seal can allow fluid leakage, leading to reduced system pressure and eventual component failure. The aftermarket replacement part cross-references JLG part number JL91474478. This seal type creates a barrier between two surfaces to prevent fluid or contaminant passage. Over time, exposure to heat and pressure can cause the seal material to harden and crack. A failed seal often results in visible drips or a gradual loss of operating performance. Keeping a seal in sound condition helps maintain consistent system integrity. Verify the serial number or application, then call (562) 693-7748.
