The GRACO 288177 Kit, Needle Assembly, .055 is a replacement needle and nozzle assembly designed for use in GRACO spray equipment. It is engineered for medium viscosity fluids and is typically constructed with a hardened stainless steel (SST) or PEEK needle tip, depending on the specific model. This part ensures precise fluid control and reliable atomization in professional spray applications.

Key Features:

• Needle Assembly Kit
• .055 inch (1.4 mm) orifice
• Hardened SST or PEEK needle tip (model dependent)
• 12–18 oz/min (0.36–0.54 l/min) for medium viscosity fluids
• Compatible with select GRACO spray gun models (check manual for specific fitment)
• Precise fluid control for consistent spray patterns
• Durable construction for extended service life
• Easy to replace for minimal downtime
• Designed for medium viscosity materials

Applications:
Used in industrial, automotive, and protective coating applications where medium viscosity fluids are sprayed. Suitable for paints, coatings, adhesives, and other similar materials.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of your spray equipment.
• Always shut off and depressurize the fluid supply before installation
• Filter the fluid line to prevent clogging and ensure smooth operation
• Refer to the equipment manual for specific installation instructions
• Ensure all seals and washers are properly seated to prevent leaks
