Graco 166255 Packing Gland

Product Description

The GRACO 166255 is a packing gland designed for use in Graco fluid-handling and spray equipment. A packing gland secures and compresses the packing material around a reciprocating rod or plunger, maintaining a reliable seal and preventing fluid from escaping the pump chamber. This component is a direct service part used during routine maintenance or seal replacement procedures. Licensed technicians and experienced service professionals typically handle this type of repair to ensure proper seating and system integrity.

This packing gland is suited for installation in Graco pump assemblies where the original gland has worn, cracked, or failed to maintain an adequate seal. It is commonly serviced during packing kit replacements on airless spray systems and fluid transfer pumps found in commercial painting, coating, and industrial fluid-handling applications.

Key Features

• Secures packing material around the pump rod or plunger to prevent fluid bypass
• Designed as an OEM-style replacement part for Graco pump assemblies
• Supports proper seal compression for consistent pump performance
• Intended for use as part of a scheduled packing maintenance procedure

Compatibility

Designed as an OEM-style replacement packing gland for Graco fluid-handling and spray pump assemblies. Consult the Graco parts manual for your specific equipment model to confirm fitment before installation.

Installation Notes

Installation should be performed by a qualified technician familiar with Graco pump service procedures. Before servicing, relieve all fluid pressure from the system and disconnect the power source per standard lockout/tagout protocol. Avoid over-tightening the gland, as this can accelerate packing wear and damage the rod surface. Follow the applicable equipment service manual for proper torque and assembly sequence.
