Aftermarket GRACO® 25D138 Packing Set, throat L/PE (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 75414

Comparable OEM Part Number: 25D138

Description: Total Finishing's part # 20-3437 is a direct-fit replacement throat package set for the GRACO® Xtreme 290cc L/PE airless sprayer. This component seals and supports the pump's fluid intake pathway, directly impacting spray consistency and material flow during high-volume coating applications.

Spray equipment technicians and professional contractors rely on throat package sets to restore proper fluid dynamics when wear or material buildup compromises intake performance. Replacing the complete set during pump rebuild service ensures all sealing surfaces engage correctly and eliminates the risk of partial functionality from mismatched components.

Common reasons for replacement:

• Material restrictions or flow blockages reducing pressure output below specification
• Worn sealing surfaces allowing fluid bypass or loss of prime
• Hardened or degraded intake components from prolonged solvent exposure
• Performance degradation requiring full intake pathway restoration during scheduled maintenance

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