The GRACO 16B285 SEAL, POSIPACK, 4.25, ZAP is a precision-engineered seal designed for use in GRACO fluid handling systems. Its primary function is to maintain the integrity of the equipment by preventing fluid leaks, ensuring leak-free operation and safeguarding the efficiency of the machinery. The material is not specified in available documentation, but similar GRACO Posipack seals are typically made from durable elastomers or engineered plastics for chemical and pressure resistance.

Key Features:

• Seal, Posipack
• Designed for specific GRACO fluid handling systems; verify rod nominal size matches seal prior to installation
• Precision fit for leak-free operation
• Engineered for reliability and durability
• Individually packaged with part number and size for easy identification
• Designed for easy maintenance and replacement

Applications:
Used in GRACO fluid handling and dispensing systems, particularly in metering and dispensing valves for sealants, adhesives, and other fluids. Suitable for professional and industrial environments where leak prevention and equipment integrity are critical.

Installation Notes:

• Using genuine GRACO replacement parts ensures optimal performance, leak-free operation, and equipment longevity. Non-genuine parts may compromise system integrity and safety.
