The GRACO 556563 is an O-ring made from VITON-A 75 DURO material, designed to provide a reliable seal in GRACO equipment, particularly in vacuum sight applications. Its primary function is to prevent leaks and ensure proper sealing within compatible GRACO systems.

Key Features:

• O-ring
• -213 VITON-A 75 DURO
• VITON-A (fluorocarbon elastomer), 75 DURO (hardness)
• Designed for use in GRACO vacuum sight and related equipment
• High chemical resistance due to VITON-A material
• Durable construction for reliable sealing
• Factory stock part for easy replacement

Applications:
Used in GRACO vacuum sight assemblies and other compatible GRACO equipment where a robust, chemical-resistant seal is required.

Installation Notes:

• Using genuine GRACO O-rings ensures optimal sealing performance, equipment longevity, and safety.
• Inspect the O-ring for damage or wear before installation
• Ensure the mating surfaces are clean and free of debris
• Lubricate the O-ring with a compatible lubricant if recommended by the equipment manual
• Install the O-ring carefully to avoid pinching or twisting
• Regularly inspect O-rings for signs of wear or degradation
• Replace O-rings during routine maintenance or if leaks are detected
