Manufacturer: Total Finishing Supplies

Part Number: 300120

Comparable OEM Part Number: 100040

Description: Total Finishing's part # 12-1483 is a direct-fit replacement for the GRACO® 100040 plug. It is a threaded plug used to seal unused ports on manifolds, filter housings, and pump assemblies, preventing fluid loss and contamination during operation.

Common reasons this plug is replaced:

• Thread damage from over-torquing or repeated removal
• Corrosion or pitting from aggressive coatings and solvents
• Sealing failure causing fluid leakage at the plugged port
• Lost or missing during pump or manifold service

Service technicians install this part during routine maintenance and during diagnostic teardowns of GRACO® spray equipment when the listed failure modes appear.

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