The SprayTech 0509940 Packing Kit contains the sealing components required for pump maintenance on compatible GPX and LC series sprayer models.
Pump packing seals wear gradually due to friction, pressure cycling, and contact with coating materials. Compromised packing can result in fluid leaks, pressure inconsistencies, and reduced overall sprayer performance. Timely replacement of these seals helps maintain pump efficiency and prevents potential damage to other pump components.
