Aftermarket GRACO® 25D179 Packing Set, throat T/PE (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 75537

Comparable OEM Part Number: 25D179

Description: Total Finishing's part # 20-3443 is a direct-fit replacement for the GRACO® Throat Pkg Set designed for Xtreme 290cc TFE/PE airless spray systems. This throat package assembly houses critical wear surfaces and fluid pathways that manage paint flow and pressure regulation in high-demand coating applications. Spray equipment technicians and professional painting contractors rely on throat packages to maintain spray consistency and pressure stability during extended jobsite operations.

Common reasons for replacement:

• Erosion or scoring of internal passages from abrasive paint media, resulting in pressure loss or inconsistent spray patterns
• Seal degradation or fluid seepage around throat assembly threads indicating worn packing surfaces
• Buildup of dried coating material blocking fluid passages, requiring full package replacement rather than spot cleaning
• Pressure fluctuations or chattering during operation, a sign that throat components are no longer sealing effectively under load

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