The GRACO 17B690 is a flange and hose barb assembly designed for use with GRACO peristaltic pumps. It is typically constructed from durable materials suitable for industrial fluid handling. This part is intended to securely connect hoses to pump housings, ensuring reliable fluid transfer within GRACO equipment such as the SoloTech™ peristaltic pump series.

Key Features:

• Flange, Hose Barb
• NG1 (for ST6, ST10, ST23, ST25, ST26, ST30 peristaltic pumps; specific to I6, I10, I16, H10, H16 as referenced in product name)
• GRACO peristaltic pumps (ST6, ST10, ST23, ST25, ST26, ST30); also referenced for I6, I10, I16, H10, H16 models
• Secure hose connection
• Designed for easy installation and maintenance
• Reliable sealing with included o-ring (where applicable)
• Engineered for industrial duty cycles

Applications:
Used in industrial fluid handling systems, including lubrication, chemical transfer, and maintenance applications. Suitable for mining, agriculture, and other heavy-duty environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal compatibility, performance, and safety within GRACO equipment.
• Orient the hose clamp so the clamp housing aligns with the recessed cavity in the pump housing.
• Slide the hose clamp over the hose, then slide on the barb assembly.
• Tighten the clamp to 25 ft-lb (33.9 N•m) plus one full turn, or until flush with the outer hose diameter.
• Push the hose and clamp into the pump housing.
• Attach the hose barb assembly to the pump using nuts and torque to the specified value (e.g., 8 ft-lb for ST6, ST10, ST23, ST25; 18 ft-lb for ST26, ST30).
• Loop the hose 360 degrees and insert the second end through the opposite side port.
• Repeat installation steps for the second end.
• Move the roller as per pump instructions to install the hose.
