The GRACO 131425 is a Belleville washer, a type of conical spring washer designed to provide a reliable spring force in bolted assemblies. Its material is not specified in available sources, but Belleville washers are typically made from hardened steel or stainless steel. This part is intended for use within GRACO equipment to maintain tension and prevent loosening of fasteners under vibration or thermal cycling.

Key Features:

• Belleville (conical spring) washer
• Designed for use in GRACO equipment; specific compatibility should be confirmed with equipment manual or GRACO specialist
• Provides consistent spring force
• Helps maintain bolt tension under vibration or thermal cycling
• Reliable performance in demanding environments

Applications:
Used in GRACO equipment assemblies where maintaining bolt tension is critical, such as in lubrication systems, pumps, and other industrial machinery.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety of equipment. Non-genuine parts may not meet specifications and could lead to equipment failure.
• Ensure the washer is installed with the correct orientation (convex side typically facing the bolt head or nut)
• Tighten fasteners to the recommended torque specified in the equipment manual
• Inspect washers for wear or deformation during routine maintenance
• Regularly check for signs of wear, corrosion, or loss of spring force
• Replace washers if they become flattened or damaged
• Follow GRACO’s recommended maintenance schedule for the specific equipment
