The GRACO 27421 SHAFT COUPLER-3/4-16 THD is a precision-engineered mechanical component designed to connect shafts within GRACO equipment. Its material is not explicitly specified, but it is built to GRACO’s high standards for durability and reliability. This part is intended to ensure secure and efficient transmission of rotational motion between connected shafts in industrial fluid handling systems.

Key Features:

• Shaft Coupler
• 3/4-16 THD
• Designed for use with GRACO equipment requiring a 3/4-16 threaded shaft connection
• Precision-engineered for secure shaft connection
• Built to GRACO’s high quality and reliability standards
• Ease of maintenance and replacement

Applications:
Used in industrial fluid handling and spray equipment where reliable shaft coupling is required, such as in paint sprayers, lubrication systems, and other GRACO machinery.

Installation Notes:

• Using a genuine GRACO part ensures compatibility, reliability, and optimal performance of the equipment. Non-genuine parts may compromise safety and equipment longevity.
• Ensure equipment is powered off and depressurized before installation
• Align shafts properly before tightening the coupler
• Follow torque specifications if provided in the equipment manual
