The GRACO 16Y278 is a flat washer designed for use in GRACO equipment. It is typically made from metal (exact material not specified in available sources) and serves as a standard hardware component to distribute load and prevent damage to surfaces during assembly or maintenance.

Key Features:

• Flat washer
• M18 (likely refers to the nominal diameter for compatibility with M18 bolts, but exact size may vary; some sources list dimensions as 1.25 in x 1.25 in, but this may not be standard for M18 washers)
• Designed for use with GRACO equipment, particularly where M18 bolt sizes are required
• Standard flat washer design for load distribution and surface protection; ease of replacement and maintenance

Applications:
Used in the assembly and maintenance of GRACO spray equipment and other machinery where M18 bolts are utilized.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and longevity of equipment, reducing the risk of leaks, misalignment, or equipment failure.
• Ensure the washer is placed between the bolt head/nut and the surface to be protected. Tighten bolts to manufacturer-recommended torque specifications. Inspect washers for wear or damage during routine maintenance.
• Regularly check and replace washers as part of preventive maintenance. Use only genuine GRACO parts for optimal performance and safety.
