The GRACO 194358 PLUG is a threaded plug made from polypropylene, designed to seal or block off 1/2-14 NPT (National Pipe Thread) ports in GRACO equipment, particularly in air-operated diaphragm pumps and related fluid handling systems.

Key Features:

• Plug
• 1/2-14 NPT
• Polypropylene (ACTEAL NPT also referenced in some listings)
• Compatible with GRACO air-operated diaphragm pumps and systems requiring 1/2-14 NPT threaded ports
• Threaded for secure fit
• Corrosion-resistant material
• Reliable sealing for fluid systems

Applications:
Used to seal unused ports in GRACO air-operated diaphragm pumps and fluid handling equipment, preventing leaks and contamination.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, seal integrity, and compatibility with GRACO equipment, reducing the risk of leaks and equipment failure.
• Ensure threads are clean and free of debris before installation
• Hand-tighten the plug, then use appropriate tools to achieve a secure fit without overtightening
• Check for leaks after installation
• Inspect plugs periodically for wear or damage
• Replace if signs of cracking, deformation, or leakage are observed
