The GRACO 180981 COVER, DIAPHRAGM is a protective component designed to encase and support the diaphragm within GRACO fluid regulators. Its material is not specified in available documentation, but it is intended to ensure proper operation and longevity of the diaphragm assembly in air-operated fluid regulation systems.

Key Features:

• Diaphragm Cover
• 6.8 IN x 6.8 IN (approximate, based on diaphragm dimensions; cover size not explicitly stated but likely matches diaphragm size)
• Compatible with GRACO fluid regulators using diaphragm part number 180979 and related assemblies
• Protects and supports diaphragm assembly
• Facilitates maintenance and replacement of diaphragm
• Designed for reliability in fluid regulation systems

Applications:
Used in GRACO air-operated fluid regulators for precise control of downstream fluid pressure in industrial and maintenance applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment.
• Refer to the equipment manual for specific installation instructions
• Ensure all components are clean and free of debris before assembly
• Follow recommended torque specifications for fasteners (e.g., 35–40 ft-lb for related components as per manual)
• Use appropriate thread sealant (e.g., Loctite TL-242 or 601) where specified
