The GRACO 112119 VALVE, PRESSURE RELIEF is a safety component designed to prevent overpressurization in fluid handling systems. It is typically constructed from durable materials suitable for industrial environments, though the specific material is not specified in available sources. Its primary function is to protect pumps and hoses from rupture due to excessive pressure, especially in scenarios involving thermal expansion or fluid backup in outlet lines[5][2][4].

Key Features:

• Pressure relief valve
• 112119
• 150 PSI (10.3 bar) (for similar GRACO fluid pressure relief kits; confirm for exact model)[5]
• Designed for use with GRACO equipment, including Husky plastic pumps (models: 307, 515, 716, 1050, 1590, 2150, 3275)[5]
• Prevents overpressurization and equipment damage
• Suitable for industrial and commercial applications
• Reliable safety mechanism for fluid handling systems

Applications:
Used in fluid handling systems where overpressurization is a risk, such as in lubrication, paint, or chemical transfer applications. Particularly important in systems with long fluid lines exposed to temperature changes or when feeding fluid to piston pumps[5].

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and safety in critical applications.
• Install at the pump outlet to prevent overpressurization
• Ensure proper orientation and secure mounting
• Regularly inspect for leaks or damage
• Follow manufacturer guidelines for maintenance and replacement
• Consult the equipment manual for specific installation instructions
• Use only GRACO-approved replacement parts
• Monitor system pressure regularly
