The GRACO 562639 is a check valve designed to allow fluid flow in one direction while preventing backflow. It is constructed from carbon steel (CS) and is intended for use in GRACO lubrication and fluid handling equipment to ensure reliable, unidirectional flow of lubricants or other compatible fluids.

Key Features:

• Check Valve
• 1/4T x 1/8NPT
• Carbon Steel (CS)
• Designed for use with GRACO lubrication and fluid handling systems
• Prevents backflow in lubrication systems
• Durable carbon steel construction for longevity
• Standard NPT thread connections for easy integration

Applications:
Used in lubrication systems for industrial machinery, automotive, and maintenance equipment where unidirectional flow is required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within GRACO systems.
• Ensure threads are clean and free of debris before installation
• Use appropriate thread sealant or tape as recommended for the application
• Tighten securely but avoid over-torquing to prevent damage
• Inspect regularly for leaks or wear and replace as needed
