The 17D877 is a packing O-ring designed for use in GRACO equipment, specifically for sealing and preventing leaks in fluid handling systems. The material is not explicitly stated, but it is likely a durable elastomer such as nitrile or similar, given its application as an O-ring. It is intended for use in GRACO rotary applicators, particularly in 50 mm models, to ensure proper sealing and reliable operation.

Key Features:

• O-Ring
• FX75, 50 mm models only
• GRACO ProBell Rotary Applicator, 50 mm models
• Designed for reliable sealing in high-speed rotary applicators
• Supports equipment with up to 60,000 RPM turbine speeds
• Ease of maintenance: accessible for replacement during routine service

Applications:
Used in GRACO ProBell Rotary Applicators for sealing fluid paths in 50 mm cup models, ensuring leak-free operation during paint or coating application.

Installation Notes:

• Using genuine GRACO O-rings ensures proper fit, sealing performance, and equipment longevity.
• Inspect O-ring for damage or wear before installation
• Ensure mating surfaces are clean and free of debris
• Lubricate O-ring with compatible lubricant if recommended by the manual
• Replace O-ring during scheduled maintenance or if leaks are detected
• Follow manufacturer’s maintenance schedule
• Use only genuine GRACO replacement parts for optimal performance
• Refer to the equipment manual for specific installation procedures
