The GRACO Backup Ring (SKU:. 124061) is a sealing component made from PTFE (polytetrafluoroethylene), designed to provide secondary support and sealing for O-rings in GRACO proportioning pumps and related equipment. Its primary function is to prevent extrusion and enhance the longevity of the main O-ring under pressure.

Key Features:

• Backup Ring
• 0.518 inch inner diameter, 0.053 inch width
• PTFE (polytetrafluoroethylene)
• Designed for use with GRACO proportioning pumps and similar equipment
• Provides secondary support to O-rings
• Reduces risk of O-ring extrusion under pressure
• Enhances seal reliability and equipment uptime

Applications:
Used in GRACO proportioning pumps and other fluid handling equipment where reliable sealing under pressure is required.

Installation Notes:

• Using genuine GRACO backup rings ensures proper fit, performance, and compatibility with GRACO equipment, reducing the risk of leaks and premature failure.
• Install the backup ring in the correct orientation as specified in the equipment manual
• Ensure both the O-ring and backup ring are clean and free from damage before installation
• Follow manufacturer-recommended procedures for cylinder assembly and disassembly
• Inspect backup rings during routine maintenance for wear or damage
• Replace backup rings whenever O-rings are replaced or if signs of extrusion or deformation are observed
