The GRACO 180957 is a piston washer, a critical component used within GRACO pumps and spray equipment. Its primary function is to provide a secure seal and support for the piston assembly, ensuring efficient operation and preventing leaks. The specific material is not specified in available documentation, but GRACO piston washers are typically made from durable materials such as stainless steel, PTFE, or other engineered polymers, depending on the application and equipment model.

Key Features:

• Washer, Piston
• Provides secure seal and support for piston assembly
• Designed for durability and reliability in high-pressure environments
• Ease of maintenance and replacement

Applications:
Used in GRACO pumps and spray equipment for industrial, agricultural, and maintenance applications where reliable piston sealing is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of equipment. Non-genuine parts may compromise seal integrity and equipment reliability.
• Ensure equipment is depressurized and isolated before installation
• Inspect the piston and cylinder for wear or damage before installing the new washer
• Follow manufacturer torque specifications for assembly
• Regularly inspect and replace washers as part of routine maintenance to prevent leaks and equipment failure
