The GRACO 17R663 is a check valve housing designed for use in fluid handling systems. It is constructed to connect via a TriClamp fitting on one end and a 1-inch NPT (National Pipe Thread) on the other, facilitating secure and leak-resistant connections in industrial applications. The material is not specified, but GRACO housings are typically made from durable metals or engineered plastics for reliability and chemical resistance. This part is intended to house check valves within GRACO equipment, ensuring proper flow direction and preventing backflow in fluid transfer systems.

Key Features:

• Check Valve Housing
• TriClamp/1NPT
• Designed for use with GRACO fluid handling systems and compatible with TriClamp and 1-inch NPT fittings
• Secure TriClamp and NPT connections for leak resistance
• Engineered for reliability in industrial environments
• Ease of maintenance due to standard fitting types

Applications:
Used in industrial fluid handling systems, including lubrication, chemical transfer, and process applications where check valve functionality is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and safety in your equipment.
• Ensure proper alignment of TriClamp and NPT connections before tightening
• Inspect O-rings and seals for wear or damage prior to installation
• Follow GRACO equipment manual for torque specifications and installation procedures
• Regularly inspect for leaks or wear
• Replace seals and O-rings as needed during maintenance
• Use only compatible fittings and accessories
