The GRACO 15T311 Nut Coupler is a mechanical component designed to securely connect and fasten coupling elements within GRACO equipment, particularly in displacement pump assemblies. Its material is not specified in available documentation, but it is typically made from durable metal alloys for strength and longevity. The part is intended to ensure a reliable and leak-free connection between pump components, supporting the efficient operation of GRACO pumps.

Key Features:

• Nut, Coupler
• 15T311
• Compatible with GRACO displacement pumps, including Merkur series (e.g., LW025x and other pump sizes)
• Designed for secure fastening and reliable connection
• Supports efficient pump operation
• Ease of maintenance due to standardized design

Applications:
Used in GRACO displacement pump assemblies to connect and secure coupling elements, ensuring leak-free and efficient pump operation. Commonly found in industrial lubrication and fluid handling systems.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the equipment. Non-genuine parts may compromise safety and efficiency.
• Ensure proper alignment of coupling elements before tightening the nut coupler
• Tighten to recommended torque specifications (refer to equipment manual for specific values)
• Inspect for wear or damage before installation and replace if necessary
• Follow all safety procedures outlined in the GRACO equipment manual
