SEAL KIT -FOR 9103-3371 (JLG JL91034278)

JL91034278: A damaged seal kit can allow fluid leaks that reduce system pressure and cause erratic operation. This aftermarket replacement references the JLG catalog number JL91034278 and cross-references the OE part 9103-3371. The seal kit contains multiple sealing elements that prevent fluid bypass between moving components. A common failure consequence is gradual loss of pressure, leading to slower or incomplete actuation. During a rebuild, worn seals often show visible cracking or hardening from age and heat exposure. The item ships at approximately 0.4 pounds. Verify the serial number or application, then call (562) 693-7748.
