The GRACO 17Y549 is a specially shaped O-ring designed for high-pressure applications, used to seal the connection between the head and other components in GRACO equipment. Its durable construction ensures a tight, reliable seal, preventing leaks and maintaining smooth operation. The material is not explicitly stated, but it is typically made from a high-grade elastomer suitable for wear and chemical resistance.

Key Features:

• O-ring, Head, Formed, Square
• Height: 0.1 in (0.254 cm), Length: 2.75 in (6.985 cm), Width: 2.75 in (6.985 cm)
• Designed for high-pressure applications
• For use with GRACO equipment requiring a formed, square head O-ring
• Specially shaped for precise fit and sealing
• Withstands extreme wear and high-pressure environments
• Ensures consistent, leak-free operation

Applications:
Used in GRACO spray equipment to seal the head assembly, ensuring reliable performance in demanding industrial and maintenance environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal fit, performance, and longevity of equipment.
• 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 if leaks or deterioration are detected
• Regularly inspect O-rings for signs of wear or damage
• Replace O-rings as part of routine maintenance to prevent leaks and downtime
• Use only genuine GRACO replacement parts for best results
