The GRACO 563954 Blowout Disc Kit consists of 25 yellow blowout discs designed for use as rupture-to-atmosphere indicators in lubrication systems. These discs are engineered to burst at a specified pressure, providing a safety mechanism to prevent over-pressurization in GRACO equipment. The material is not explicitly specified, but blowout discs are typically made from a thin, pressure-sensitive material such as metal or composite.

Key Features:

• Blowout Disc Kit
• 3/8 in. diameter, 25 pieces per kit
• 1450 psi (burst pressure)
• For use with 1/8" NPTF rupture-to-atmosphere indicators in GRACO lubrication systems
• Easy to replace
• Reliable pressure relief
• Color-coded for quick identification (yellow)
• Sold in convenient kits for maintenance efficiency

Applications:
Used as safety devices in GRACO lubrication systems to prevent over-pressurization by rupturing at a set pressure, protecting equipment and operators.

Installation Notes:

• Using genuine GRACO blowout discs ensures proper fit, reliable performance, and maintains system safety standards.
• Ensure the system is depressurized before replacing discs
• Inspect the rupture-to-atmosphere fitting for damage or debris
• Replace discs in accordance with maintenance schedules or after any over-pressurization event
• Use only discs rated for the correct pressure and application
• Regularly inspect and replace blowout discs as part of routine maintenance
• Keep spare kits on hand for quick replacement
• Follow all safety procedures when working with pressurized systems
