SEAL KIT - VALVE (JLG JL44979GT)

A damaged valve seal kit can allow internal leakage that reduces system pressure and causes erratic actuator movement. During disassembly, a worn seal kit often reveals hardened or cracked elastomers that no longer hold pressure. The seal kit contains multiple O-rings, backup rings, and wiper seals that isolate fluid passages within a valve body. Keeping these sealing elements in sound condition helps maintain consistent flow control and prevents cross-port leakage. This aftermarket replacement part references the JLG catalog number JL44979GT. Verify the serial number or application, then call (562) 693-7748. A failed seal kit may also introduce contamination into the fluid, accelerating wear on other components.
