The GRACO 557437 is a replacement rupture disk designed for use in GRACO equipment. It is a safety component intended to protect systems from overpressure by rupturing at a specified pressure. The disk is typically made from a thin, engineered material (exact material not specified), and its pink color indicates its pressure rating. It is used in various GRACO lubrication and fluid handling systems to ensure safe operation.

Key Features:

• Rupture disk
• 11/16 inch diameter
• 2650 psi (maximum working pressure)
• Designed for use in GRACO equipment requiring 11/16" diameter rupture disks rated at 2650 psi
• Color-coded for easy identification of pressure rating
• Reliable overpressure protection
• Easy to replace as part of routine maintenance

Applications:
Used in GRACO lubrication and fluid handling systems to protect against overpressure and ensure safe operation. Suitable for industrial, mining, and agricultural applications where reliable pressure relief is required.

Installation Notes:

• Using genuine GRACO replacement parts ensures proper fit, performance, and safety in critical applications.
• Always replace rupture disks with the correct pressure rating and size as specified by the equipment manual.
• Inspect the disk and seating area for damage or debris before installation.
• Follow all safety procedures and equipment shutdown protocols when replacing rupture disks.
• Ensure proper torque and alignment during installation to prevent leaks or premature failure.
