The GRACO 24W504 is a carbon steel grease injector manifold designed for automated lubrication systems. It is intended for use in distributing grease to multiple lubrication points in heavy-duty equipment, such as on-road vehicles and off-road machinery.

Key Features:

• Grease Injector Manifold
• GL-33, 4 Injector Manifold, 1/8 in. BSPP x 6 mm
• Carbon Steel
• Operating pressures: 1200–3500 psi (83–241 bar)
• Compatible with NLGI #2 grease; suitable for single line parallel metering devices
• One-piece, machined body for exceptional durability
• Longer-lasting seal design for trouble-free performance
• Precision-honed components for reliable operation in challenging environments
• Adjustable output volume (0.001–0.003 in³ or 0.02–0.05 cm³ per injector)
• Convenient front-mounted visual indicator pin
• Easy to add or subtract lube points without redesigning the system

Applications:
On-road vehicles, off-road equipment, and other heavy-duty machinery requiring automated, multi-point lubrication.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and longevity of the lubrication system.
• Ensure all connections are clean and free of debris before installation
• Use appropriate thread sealant for BSPP connections
• Follow manufacturer-recommended torque specifications
• Verify system pressure is within the specified range (1200–3500 psi)
• Regularly inspect for leaks and proper injector operation
• Perform preventative maintenance to ensure peak performance and longevity
• Monitor visual indicator pins for proper cycling
• Replace seals and components as recommended by GRACO
