The GRACO 189409 is a stainless steel (SST) ball housing component designed for use within GRACO industrial equipment, specifically as part of the ball guide assembly in high-pressure fluid handling systems. Its primary function is to securely house and guide the piston ball, ensuring reliable operation and fluid containment in demanding environments.

Key Features:

• Ball Housing
• Stainless Steel (SST)
• Compatible with GRACO industrial equipment requiring ball housing components; specific models not listed
• Durable stainless steel construction for corrosion resistance
• Designed for reliable performance in high-pressure environments
• Ease of maintenance as part of a modular assembly

Applications:
Used in industrial fluid handling systems, including lubrication, paint, and chemical transfer applications where high-pressure and reliable sealing are required.

Installation Notes:

• Using genuine GRACO parts ensures optimal fit, performance, and safety in high-pressure systems.
• Always follow the equipment manual for installation procedures
• Ensure proper alignment and lubrication of components during assembly
• Use appropriate tools and avoid hammering sensitive parts; a rubber mallet is recommended for certain installations
• Regularly inspect for wear or corrosion
• Replace as part of scheduled maintenance or when signs of degradation are observed
• Use only compatible replacement parts to maintain system integrity
