The GRACO 114905 is a set of five GL-1™ grease injectors with a manifold, designed for automatic lubrication systems. These injectors are constructed for rugged, high-pressure environments and are intended to deliver precise grease lubrication to multiple points within industrial equipment. The material is not explicitly specified, but the design is robust for harsh operating conditions.

Key Features:

• Grease injector set with manifold
• GL-1, 5 injectors and manifold (114905)
• Rugged, single-piece uni-body design; fully enclosed press fittings
• Output volume per cycle: 0.008–0.08 in³ (0.13–1.13 cm³)
• Maximum operating pressure: 3,500 psi (241 bar); Minimum operating pressure: 1,850 psi (128 bar); Suggested operating pressure: 2,500 psi (172 bar); Reset pressure: 600 psi (4.1 bar)
• Recommended fluids: Grease NLGI grade #1 or lighter; Can be combined with GL-11 and GL-32 injectors in the same system
• Adjustable hex head nut for easy output adjustment
• No vent holes and fully enclosed press fittings to prevent leaks
• Top-mounted cycle pin indicator for quick function confirmation
• Captured seal design for long seal life (no leakage at 215,000 cycles)
• Reliable operation in harsh environments
• Easy customization for various applications

Applications:
Used in automatic lubrication systems for industrial machinery, mining, agriculture, and other demanding environments where reliable, high-pressure grease delivery is required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Relieve system pressure before installation or maintenance (see pump instruction manual for procedure)
• Install injectors according to the system layout and manifold configuration
• Ensure all fittings are securely tightened to prevent leaks
• Regularly check cycle pin indicator for proper injector function
• Follow recommended operating pressures and grease specifications
• Inspect seals and fittings periodically for wear or leaks
• Replace seals as needed using genuine GRACO repair kits
• Keep injectors clean and free from debris
