Part 9904302 is a replacement outlet plug used in hydraulic and fluid systems on compatible Elite and PowrLiner line stripers. This plug seals unused ports in manifolds, pumps, and valve bodies, preventing fluid leaks and contamination ingress. When the original plug becomes damaged, stripped, or corroded, replacement restores proper system sealing.

The 9904302 outlet plug is a direct replacement sealing component for Elite 3500, Elite 3500 72v, PowrLiner 3000, PowrLiner 3500s, and PowrLiner 3500 72v (including Honda gxe version) line stripers. This plug is used to seal unused outlet ports in hydraulic manifolds, pump bodies, and valve assemblies. It prevents fluid leakage, keeps contaminants out of the system, and maintains proper operating pressure. Manufactured from corrosion-resistant materials with precision threads, this plug ensures a positive seal even under high-pressure conditions. A damaged, stripped, or corroded plug can cause fluid loss, pressure drops, and system contamination. Replacing with this plug restores system integrity and prevents costly fluid loss. The hex drive allows easy installation with standard tools. Regular inspection during maintenance helps identify plugs that may be compromised.
