The GRACO 24A921 GL-32™ Grease-Injector is a single-injector manifold made from carbon steel, designed for reliable and adjustable grease delivery in automatic lubrication systems. It is intended for use in on-road vehicles and off-road equipment, providing accurate lubrication to critical points within GRACO equipment.

Key Features:

• Grease Injector
• GL-32, 1-Injector Manifold, 1/4 NPT
• Carbon Steel
• Adjustable output volume from .001–.008 in³ (0.02–0.13 cm³) per cycle (based on GL-32 model features; not explicitly specified for 24A921, but consistent with GL-32 series)
• Minimum: 750 psi (5.3 MPa), Maximum: 3500 psi (24.1 MPa)
• Compatible with grease up to NLGI #2 grade; compatible with single line parallel metering devices
• One-piece design for easy setup and modification
• Visual cycle pin indicator for quick function confirmation
• Longer lasting seal design for trouble-free performance
• Precision-honed components for reliable operation in challenging environments
• Adjustable output volume to fit system needs
• Easy to add or subtract lube points without redesigning the system

Applications:
On-road vehicles, off-road equipment, and other machinery requiring reliable, automatic grease lubrication.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within GRACO lubrication systems.
• Ensure proper alignment and secure connection of the 1/4 NPT inlet
• Verify that the system pressure is within the specified range (750–3500 psi)
• Use compatible grease (up to NLGI #2)
• Regularly check the cycle pin indicator for proper injector function
• Follow manufacturer guidelines for maintenance and inspection
