The GRACO 557507 is a set of enclosure plug gaskets designed for use with Trabon MD Divider Valves. These gaskets are typically made from fluoroelastomer (FKM) or similar elastomeric materials, ensuring a reliable seal for the enclosure plugs in divider valve assemblies. Their primary function is to prevent lubricant leakage and maintain system integrity within GRACO automatic lubrication systems.

Key Features:

• Enclosure Plug Gasket
• Fluoroelastomer (FKM) or similar elastomeric material (inferred from standard Trabon MD seals)
• Compatible with Trabon MD Divider Valve assemblies
• Reliable sealing for enclosure plugs
• Designed for high-temperature and synthetic lubricant applications
• Easy to replace during maintenance
• Supports system integrity and leak prevention

Applications:
Used in automatic lubrication systems for industrial machinery, including mining, agriculture, and manufacturing equipment. Ensures reliable sealing of enclosure plugs in divider valve assemblies, preventing lubricant leakage and maintaining system performance.

Installation Notes:

• Using genuine GRACO enclosure plug gaskets ensures proper fit, seal integrity, and long-term reliability of the lubrication system. Non-genuine parts may compromise system performance and lead to leaks or failures.
• Inspect gasket and mating surfaces for damage before installation
• Ensure surfaces are clean and free of debris
• Tighten enclosure plug to recommended torque (for Trabon MD/MSP, typically 12-15 ft lbs for piston enclosure plugs, but confirm with specific valve documentation)
• Check for leaks after installation and during routine maintenance
• Regularly inspect gaskets for wear or damage
• Replace gaskets during scheduled maintenance or if leaks are detected
• Use only recommended lubricants and compatible gasket materials
