The GRACO 557333 is a reservoir gasket designed for use in GRACO lubrication equipment. It is typically made from a durable sealing material (exact material not specified in available sources) and is intended to provide a reliable seal for the reservoir of 6, 12, and 20 lb. capacity systems, ensuring leak-free operation and maintaining system integrity.

Key Features:

• Reservoir Gasket
• Fits 6, 12, and 20 lb. reservoirs
• Compatible with GRACO lubrication systems using 6, 12, or 20 lb. reservoirs; also referenced by Lubriquip part number 501-423-000 and Trabon part number 1423
• Provides a reliable seal for reservoir caps, supports ease of maintenance and replacement, and is essential for leak prevention in lubrication systems

Applications:
Used in GRACO lubrication equipment for sealing reservoirs in floor mount or wall mount pump packages, ensuring proper lubrication supply to pump components in industrial and maintenance applications.

Installation Notes:

• Using genuine GRACO gaskets ensures proper fit, seal integrity, and equipment reliability, reducing the risk of leaks and downtime.
• During installation, remove and discard old gaskets. Install the new gasket (557333) on top of the adapter tube, then secure the reservoir cap. Torque nuts to 5 ft-lbs (6.78 N•m) for proper sealing. Always follow the equipment manual for detailed instructions.
• Inspect gasket for damage before installation. Replace gasket during routine maintenance or if leaks are detected. Use only genuine GRACO parts for optimal performance and safety.
