The GRACO 121504 O-Ring is a sealing component made from PTFE (polytetrafluoroethylene), designed to provide reliable sealing in various GRACO pump assemblies, particularly for Husky 3300 series pumps. Its primary function is to prevent leaks and ensure efficient operation of fluid handling equipment.

Key Features:

• O-Ring
• PTFE (polytetrafluoroethylene)
• Compatible with GRACO Husky 3300 series pumps (see model list in product kits for specific compatibility)
• High chemical resistance due to PTFE material
• Reliable sealing for demanding industrial applications
• Long service life and durability

Applications:
Used in GRACO Husky 3300 series pumps for sealing critical joints and preventing leaks in fluid transfer systems. Suitable for use in various industries including mining, agriculture, and manufacturing.

Installation Notes:

• Using genuine GRACO O-rings ensures proper fit, performance, and longevity of the equipment. Non-genuine parts may compromise sealing and lead to equipment failure.
• Inspect O-ring for damage before installation
• Ensure mating surfaces are clean and free of debris
• Lubricate O-ring with compatible lubricant if recommended by the manufacturer
• Follow GRACO pump assembly instructions for correct placement
• Regularly inspect O-rings for wear or degradation
• Replace O-rings during scheduled maintenance or at first sign of leakage
• Use only GRACO-approved replacement parts
