• 1.80 x 1.38
• Compatible with GRACO fluid pumps and suction tube assemblies as referenced in GRACO manuals
• Designed for secure attachment of suction tube assemblies
• Facilitates easy maintenance and replacement of suction components
• Reliable sealing for consistent fluid transfer

Applications:
Used in GRACO airless sprayers and fluid pumps to connect and seal suction tube assemblies, ensuring proper priming and fluid flow during operation.

Installation Notes:

• Using a genuine GRACO suction nut ensures proper fit, seal, and reliable operation, reducing the risk of air leaks and equipment failure.
• Remove the suction tube assembly from the fluid pump by unscrewing the suction nut using the appropriate tool (e.g., packing adjustment tool or wrench)
• Ensure O-rings and seals are in good condition before reassembly
• Tighten the suction nut securely to prevent air leaks, but avoid over-tightening to prevent damage to threads or seals
• Check for leaks after installation and during operation
• Regularly inspect the suction nut and associated seals for wear or damage
• Replace O-rings and seals as needed to maintain a tight seal
• Clean threads and mating surfaces before reassembly
