Aftermarket GRACO® 25D176 Packing Set, throat T/PE (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 75528

Comparable OEM Part Number: 25D176

Description: Total Finishing's part # 20-3416 is a direct-fit replacement for the Throat Seal Packing Set TFE, a critical component in GRACO® airless spray pump assemblies where the fluid rod passes through the pump head.

Pump rebuild specialists and spray equipment service technicians rely on throat seal packing sets to prevent fluid leakage around the rod interface and maintain system pressure integrity during operation. When this packing deteriorates or fails, fluid begins seeping from the pump head, reducing spray output and creating cleanup issues on job sites.

Common reasons for replacement:

• Visible fluid weeping or dripping from the pump head throat area during or after spraying operations
• Loss of prime or difficulty maintaining consistent pressure after equipment sits idle
• Packing material degradation from exposure to incompatible fluids or extended pump runtime
• Routine replacement as part of scheduled pump rebuild service to restore equipment to like-new condition

Manufactured to OEM-equivalent dimensions for proper fit and performance.
