Description: Total Finishing's part # 12-1482 is a direct-fit replacement for the GRACO® 100721 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.
