The GRACO 114902 GL-1™ Grease Injectors are precision-engineered components designed for use in automatic lubrication systems. They are typically constructed from robust materials suitable for harsh industrial environments and are intended to deliver high-volume grease output at high pressures for demanding lubrication applications.

Key Features:

• Grease injector for automatic lubrication systems
• GL-1™ (2 injectors and manifold included)
• Precision-honed components for reliable operation in harsh environments
• Output volume per cycle: 0.008–0.08 in³ (0.13–1.13 cm³)
• Maximum operating pressure: 3500 psi (241 bar); Minimum operating pressure: 1850 psi (128 bar); Suggested operating pressure: 2500 psi (172 bar); Reset pressure: 600 psi (4.1 bar)
• Recommended fluids: Grease NLGI grade #1 or lighter
• Captured seal design for superior leak resistance (no seal leakage at 215,000 cycles)
• Seals last 5 times longer than competitors
• Visual cycle indicator
• Can be combined with GL-11 and GL-32 injectors in the same single line parallel system for a full range of outputs
• Reliable operation in harsh environments
• Easy to maintain and replace

Applications:
Used in automatic lubrication systems for high-pressure, high-volume grease delivery in demanding industrial, mining, agricultural, and vehicle service environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety in lubrication systems.
• Ensure system is depressurized before installation or maintenance
• Follow manufacturer’s recommended operating pressures and fluid types
• Regularly inspect seals and components for wear
• Combine with other GL series injectors as needed for system flexibility
