The GRACO 563958 Blowout Disc Kit contains 25 pink blowout discs designed for use as rupture-to-atmosphere indicators in GRACO equipment. These discs are engineered to burst at a specific pressure, providing a visual safety indicator and protecting equipment from overpressure. The discs are typically made from a durable, pressure-sensitive material suitable for industrial environments.

Key Features:

• Blowout Disc
• 3/8 in. diameter
• 2650 psi (burst pressure), Maximum Working Pressure: 6400 psi (system rating, not disc burst)
• For use with 1/8" NPTF rupture-to-atmosphere indicators in GRACO equipment
• Easy to replace
• Reliable pressure indication
• Designed for industrial duty cycles
• Color-coded for quick identification

Applications:
Used as safety indicators in high-pressure fluid handling systems, particularly in lubrication, hydraulic, and spray equipment where overpressure protection is required.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and safety in high-pressure applications.
• Ensure the system is depressurized before replacing the disc.
• Inspect the disc seat for debris or damage before installation.
• Replace discs at recommended intervals or after any overpressure event.
• Always use discs rated for the correct pressure and application.
