The GRACO 114901 GL-1™ Grease Injector and Manifold is a robust, precision-engineered component designed for automatic lubrication systems. It is constructed from high-quality materials for durability and is intended to deliver precise grease volumes to lubrication points in demanding industrial environments.

Key Features:

• Grease injector and manifold
• GL-1™
• Rugged, single-piece uni-body design
• 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)
• Compatible with GL-11 and GL-32 injectors in the same single line parallel system; Recommended fluids: Grease NLGI grade #1 or lighter (some sources list up to NLGI #2)
• Seals last 5 times longer than competitors
• No vent holes and fully enclosed press fittings to prevent leaks
• Adjustable hex head nut for easy output adjustment
• Top-mounted cycle pin indicator for quick function confirmation
• Precision-honed components for reliable operation in harsh environments
• Designed for years of reliable operation in the harshest conditions

Applications:
Used in automatic lubrication systems for industrial machinery, mining, agriculture, and other heavy-duty applications requiring reliable, high-pressure grease delivery to multiple lubrication points.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure system pressure is within recommended operating range (1850–3500 psi)
• Use recommended grease types (NLGI #1 or lighter, or up to #2 as per some sources)
• Combine with other GL series injectors for increased output or system flexibility
• Regularly check cycle pin indicator for proper injector function
• Follow manufacturer guidelines for installation and maintenance to maximize seal life and system reliability
