The GRACO 559008 is a black O-ring made from Viton-75 Duro material, designed for use as a sealing component in various GRACO equipment. Its primary function is to provide a reliable, chemical-resistant seal in demanding industrial environments.

Key Features:

• O-ring
• -217 (standard size designation)
• Viton (FKM) rubber, 75 Duro (durometer hardness)
• Designed for use in GRACO equipment requiring a Viton O-ring of size -217
• Chemical resistance (especially to fuels, oils, and solvents)
• High temperature resistance
• Durable construction for long service life
• Reliable sealing performance in harsh environments

Applications:
Used as a sealing component in GRACO pumps, sprayers, and other fluid handling equipment where resistance to chemicals and high temperatures is required.

Installation Notes:

• Using genuine GRACO O-rings ensures proper fit, performance, and longevity of the equipment, reducing the risk of leaks and downtime.
• Inspect the O-ring for damage or defects before installation
• Lubricate the O-ring with a compatible lubricant if recommended by the equipment manual
• Ensure the mating surfaces are clean and free of debris
• Install the O-ring carefully to avoid twisting or pinching
• Regularly inspect O-rings for wear, cracks, or degradation
• Replace O-rings at recommended intervals or when signs of wear are detected
• Store spare O-rings in a cool, dry place away from direct sunlight and chemicals
