JC991/20018-INT: A damaged seal kit can allow fluid leakage, reducing system pressure and causing erratic cylinder movement. The JCB catalog reference for this aftermarket replacement part is JC991/20018-INT. This seal kit contains multiple sealing elements designed to contain fluid within a cylinder assembly. A common failure consequence is gradual loss of force output as seals degrade over time. During routine service, worn seals may leave visible residue on external cylinder surfaces.
