Aftermarket GRACO® 25D153 Packing Set, throat Teflon (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 75459

Comparable OEM Part Number: 25D153

Description: Total Finishing's part # 20-3422 is a direct-fit replacement for the Throat Packing Set Xtreme 220cc TFE, a critical seal assembly for GRACO®'s high-capacity airless spray equipment. This packing set maintains pressure integrity at the pump's throat bearing, preventing fluid bypass and maintaining consistent spray output during extended coating and application work.

Pump rebuild specialists and spray equipment service technicians rely on throat packing sets to restore full operational efficiency after hours of heavy-duty use. Replacing this assembly is a routine maintenance step during pump rebuilds and resealing operations for rental equipment fleets, contractor shops, and industrial spray operations.

Common reasons for replacement:

• Fluid seepage visible around the pump throat or bearing area during operation
• Loss of spray pressure that cannot be recovered through priming or fluid system adjustments
• Visible wear, compression, or cracking of the existing packing material during inspection
• Routine maintenance intervals on high-utilization Xtreme 220cc TFE units or when reopening the pump for other seal service

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