Product Overview

The Graco 15F830 Auto Nozzle and Needle Kit (0.042 in) is a genuine OEM fluid‑set replacement kit for Graco spray guns designed for light to medium fluid viscosity coatings and finishes. This kit contains a matched nozzle‑and‑needle combination that ensures stable fluid flow, precise atomization, and consistent spray performance — helping achieve smooth, professional results while reducing defects such as runs or sputtering.

Key Features

• OEM‑grade kit: Original Graco nozzle and needle set for guaranteed compatibility and fit.
• 0.042 in orifice size: Suitable for light‑ to medium‑viscosity coatings, delivering balanced flow and atomization.
• Improved spray consistency: Matched components reduce fluid fluctuations and ensure even spray pattern.
• Durable materials: Designed to withstand repeated use under pressure and exposure to coatings and solvents.
• Easy to replace: Swapping nozzle/needle kit restores tip performance without replacing the entire spray gun assembly.

Maintenance & Installation

• Ensure the spray gun fluid passages are clean and free from dried material or debris before installing the new nozzle and needle.
• Hand‑thread the nozzle carefully to avoid cross‑threading; tighten to proper torque (per gun manual) for leak‑free sealing.
• After installation, test the spray pattern with solvent to confirm even atomization and correct fluid flow before use with actual coating material.
• Clean and flush the gun thoroughly after each use — proper cleaning extends nozzle and needle life and maintains spray quality. 
• Inspect nozzle tip and needle regularly for wear, chipping or buildup — replace the kit when spray becomes uneven, sputters, or fluid flow becomes unstable.
