• Compatible with GRACO and other industry-standard equipment requiring 1/4NPT to 1/8NPT thread conversion
• Facilitates secure connection between different thread sizes
• Designed for reliable, leak-free performance
• Compact and easy to install

Applications:
Used in fluid handling systems such as paint sprayers, catalyst pumps, and other GRACO equipment where thread size conversion is required.

Installation Notes:

• Using genuine GRACO adapters ensures proper fit, performance, and safety in high-pressure or critical fluid handling applications.
