The GRACO 194363 PLUG is a threaded plug made from PVDF (polyvinylidene fluoride), designed to seal or close off 3/4-14 NPT threaded ports in GRACO equipment, particularly in air-operated diaphragm pumps. Its primary function is to provide a secure, chemical-resistant closure for fluid or air passages.

Key Features:

• Plug
• 3/4-14 NPT
• PVDF (polyvinylidene fluoride)
• Compatible with GRACO air-operated diaphragm pumps and other equipment requiring 3/4-14 NPT threaded plugs
• Chemical resistance due to PVDF material
• Threaded for secure installation
• Designed for use in harsh environments

Applications:
Used in GRACO air-operated diaphragm pumps and similar equipment to seal off unused ports, prevent leaks, and protect internal components from contamination or exposure to aggressive chemicals.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, chemical compatibility, and reliable performance in demanding applications.
• Ensure threads are clean and free of debris before installation
• Hand-tighten the plug, then use a wrench to secure, but avoid over-tightening to prevent thread damage
• Inspect for leaks after installation
