• Coupler with set screws
• 25U930
• Designed for use with GRACO equipment, particularly for flex shaft coupling in compressors and spray systems
• Easy installation and secure fit
• Reliable performance
• Designed for optimal functionality within GRACO systems

Applications:
Used in GRACO spray equipment and compressors for connecting flex shafts and transmitting motion or power between components.

Installation Notes:

• Using genuine GRACO parts ensures optimal functionality, secure fit, and reliable performance, reducing the risk of equipment failure or downtime.
• Start two set screws into the coupler before sliding it over the coupler mount.
• Ensure the key is in position before sliding the coupler over the mount.
• Push the coupler flush against the coupler mount face.
• Tighten set screws with a 1/8 in. Allen wrench to 150-160 in-lb (16.9-18 N•m).
• Align teeth and slide flex insert all the way into the coupler for proper engagement.
• Regularly inspect the coupler and set screws for wear or loosening. Ensure proper torque is maintained on set screws during installation and maintenance.
