The GRACO 24X404 GL-1 HCP is a heavy-duty grease injector designed for automatic lubrication systems. It features a rugged, single-piece body made for harsh environments and is constructed with high corrosion protection materials, offering 1,440 hours of salt spray resistance. This injector is intended for reliable, consistent delivery of grease to lubrication points in demanding industrial applications, especially where corrosion is a concern.

Key Features:

• Grease Injector
• GL-1 HCP, Four Point
• Rugged, single-piece body; high corrosion protection (1,440 hours salt spray)
• Output volume per cycle: 0.13–1.31 cm³ (0.008–0.08 in³) for GL-1/GL-1 HCP; 0.25–1.31 cm³ (0.015–0.08 in³) for GL-1 X; 0.57–5.0 cm³ (0.035–0.305 in³) for GL-1 XL (Note: 24X404 is a GL-1 HCP, so likely 0.13–1.31 cm³ per cycle)
• Maximum operating pressure: 241 bar (3,500 psi) for GL-1/GL-1 HCP; 414 bar (6,000 psi) for GL-1 X/XL (Note: 24X404 is a GL-1 HCP, so 241 bar max)
• Compatible with single line parallel automatic lubrication systems; replaces SL-1; available as single injector or up to 6-bank injector manifold assembly
• Heavy-duty hex-head adjustment nut for easy output adjustment
• No vent holes to prevent lubricant leakage
• Fully-enclosed press fittings
• Clear, polycarbonate covers (on some models) protect cycle pin indicators from contamination
• Colour-coded output spectrum sleeves for targeted output volume
• Viton seals standard for durability
• Visual cycle pin for diagnostics and troubleshooting
• Zerk fitting for diagnostics and line priming

Applications:
Heavy-duty industrial environments, including mining, milling, cement, material processing, and marine applications where high corrosion protection is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing lubrication systems.
• Ensure the system is depressurized before installation or maintenance
• Mount the injector securely using the provided manifold or mounting hardware
• Adjust output volume using the hex-head nut as required for the application
• Regularly inspect for leaks and proper operation
• Use only compatible lubricants and fittings as specified by GRACO
