The GRACO 187874 is a stainless steel pressure gauge designed for monitoring low-pressure fluids in industrial and maintenance applications. Its corrosion-resistant construction makes it suitable for use in harsh environments, and it is intended for integration with GRACO equipment to ensure accurate pressure measurement and system safety.

Key Features:

• Pressure Gauge
• Dial Diameter: 5 in (63 mm) / 2.5 in (64 mm) (note: conflicting data, but most sources cite 5 in/63 mm as standard)
• Stainless Steel
• 0–100 psi (0–7 bar, 0.7 MPa, 700 kPa)
• Designed for use with GRACO low-pressure fluid systems; 1/4 in NPT(M) connection
• Corrosion resistant
• Shatterproof glass
• Bottom mount
• Reliable for continuous monitoring
• Easy to read dial

Applications:
Used in industrial fluid handling, lubrication systems, and maintenance applications where accurate low-pressure monitoring is required. Suitable for environments where corrosion resistance and durability are essential.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and safety within GRACO equipment systems.
• Ensure the gauge is installed with the correct thread type (1/4 in NPT male)
• Mount the gauge in a visible and accessible location for easy monitoring
• Check for leaks after installation
• Use appropriate thread sealant for a secure fit
• Regularly inspect for signs of wear or damage
• Clean the gauge face for clear visibility
• Replace if glass is cracked or dial is not functioning properly
