The GRACO 1050HP Hi-Lo Manifold Seal Kit is a set of replacement seals and o-rings designed for the high/low manifold block of the Husky™ 1050HP air-operated diaphragm pump. The kit is intended to restore sealing integrity and prevent leaks in the manifold section, ensuring reliable operation of the pump. The materials of the seals and o-rings are not explicitly listed in available documentation, but typical GRACO manifold kits use materials such as PTFE, Santoprene, or Geolast for o-rings and seals, depending on the application and fluid compatibility.

Key Features:

• Seal kit for high/low manifold block
• For Husky™ 1050HP air-operated diaphragm pump
• Compatible with Husky™ 1050HP air-operated diaphragm pumps
• Restores sealing integrity in the high/low manifold block
• Prevents leaks and ensures reliable pump operation
• Designed for easy replacement and maintenance

Applications:
Used in the maintenance and repair of GRACO Husky™ 1050HP air-operated diaphragm pumps, commonly found in industrial fluid transfer applications such as lubrication, paint, and chemical transfer.

Installation Notes:

• Using genuine GRACO seal kits ensures proper fit, performance, and longevity of the pump. Non-genuine parts may compromise sealing and lead to leaks or pump failure.
• Use an o-ring pick to remove all o-rings from the spool before installation
• Clean all parts and inspect for damage before reassembly
• Apply lithium-based grease to o-rings as instructed during installation
• Reassemble the high/low valve using all parts in the seal kit
• Torque screws to 340–360 in-lb (38–41 N•m) when reattaching the high/low valve
• Reconnect main air line and air manifold hoses after installation
