KIT- SEAL (JLG JLA004-5S000)

A damaged seal kit can lead to fluid leaks that compromise system pressure and cause erratic operation. During inspection, a worn seal may show visible cracking or hardening from age or heat exposure. The seal kit from JLG is an aftermarket replacement part, cross-referenced as JLA004-5S000. This kit contains multiple seals designed to prevent fluid bypass between moving components. A common failure consequence is gradual loss of force or speed as internal leakage increases. Keeping a seal kit in sound condition helps maintain consistent performance and reduce unplanned downtime. Verify the serial number or application, then call (562) 693-7748.
