The GRACO 176108 WASHER, BACK-UP is a small, essential component designed to provide support and sealing within GRACO equipment, particularly in severe-duty displacement pumps. Its material is not explicitly specified in available sources, but it is typically made from durable metals or engineered plastics to withstand high-pressure environments. The washer is intended to ensure proper alignment and prevent leakage in critical pump assemblies.

Key Features:

• Washer, Back-Up
• Compatible with GRACO severe-duty displacement pumps and related equipment
• Supports and seals critical pump components
• Designed for reliability in high-pressure environments
• Ease of maintenance: can be replaced during routine service

Applications:
Used in GRACO severe-duty displacement pumps for applications requiring high-pressure fluid handling, such as lubrication, paint, and chemical transfer systems.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, performance, and longevity of equipment. Non-genuine parts may compromise safety and efficiency.
• Ensure equipment is depressurized and isolated before replacing the washer
• Follow manufacturer’s service manual for disassembly and reassembly procedures
• Inspect adjacent components for wear or damage during replacement
• Use appropriate tools to avoid damaging the washer or surrounding parts
• Regularly inspect washers during scheduled maintenance
• Replace washers at the first sign of wear or leakage
• Keep spare washers on hand for quick replacement
