The GRACO 15U077 is a bellows seal made from ultra-high molecular weight polyethylene (UMHW/UHMWPE), designed to provide a reliable sealing solution for the piston in air-powered Glutton pumps. Its primary function is to prevent fluid leakage and maintain pump efficiency in demanding industrial applications.

Key Features:

• Bellows seal
• 15U077
• Ultra-high molecular weight polyethylene (UMHW/UHMWPE)
• Air-powered Glutton pumps (e.g., models 220663, 220666)
• Durable UMHW/UHMWPE construction for long service life
• Designed for reliable sealing in high-duty industrial environments
• Ease of maintenance and replacement as part of routine pump service

Applications:
Used in air-powered Glutton pumps for industrial fluid transfer, lubrication, and maintenance applications, particularly in environments requiring robust and reliable sealing solutions.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with GRACO equipment.
• Follow the manufacturer’s instructions for seal installation and replacement.
• Ensure proper alignment and seating of the bellows seal during installation.
• Grease the outlet housing groove and set the nylon seal inside the groove before assembly.
• Use appropriate tools and torque settings for securing components.
• Check for signs of wear or damage to the seal and replace as needed during routine maintenance.
• Regularly inspect seals for wear or leakage.
• Replace seals as part of scheduled maintenance to prevent pump failure.
• Use only recommended lubricants and replacement parts.
