The GRACO 555716 is a square-cut O-ring made from Buna-N (Nitrile) rubber with a hardness of 70 durometer. It is designed to provide a reliable seal in various GRACO equipment, particularly in air-operated pumps and fluid handling systems, ensuring leak-free operation and resistance to oils and chemicals.

Key Features:

• O-Ring
• SQ CUT -010 BUNA 70
• Buna-N (Nitrile) rubber, 70 durometer
• Compatible with GRACO air-operated pumps and related equipment (e.g., MSA-10 and MSA-100 Air Operated Pump)
• Square-cut profile for enhanced sealing in specific applications
• Resistant to oils, fuels, and many chemicals
• Durable construction for reliable performance in industrial environments

Applications:
Used as a sealing component in GRACO air-operated pumps and fluid handling systems, such as the MSA-10 and MSA-100 Air Operated Pump, to prevent leaks and maintain system integrity.

Installation Notes:

• Using genuine GRACO O-rings ensures proper fit, seal integrity, and equipment reliability, reducing the risk of leaks and downtime.
• Inspect the O-ring for damage or deformation 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
• Refer to the specific equipment manual for detailed installation instructions
• Regularly inspect O-rings for wear, cracks, or degradation
• Replace O-rings during routine maintenance or if leaks are detected
• Use only genuine GRACO replacement parts for optimal performance
