Graco 15F854 Large Packing Tip

Product Overview

The Graco 15F854 Large Packing Tip is a genuine OEM packing/tip component for Graco spray‑/foam guns, used when a “large tip” packing set‑up is required (e.g. for high‑yield or high‑flow applications such as stud‑wall foam, heavy coatings, or high‑volume spraying). It seals and guides the tip assembly to ensure proper fluid flow, prevent leaks, and maintain consistent performance under heavy‑duty conditions.

Key Features

• OEM‑grade part: Genuine Graco packing tip for correct fit and reliable performance.
• Large‑tip compatible: Designed to accommodate large‑tip assemblies in high‑flow or “stud‑wall” kits for heavy‑duty spraying/foam work. 
• Ensures seal integrity: Helps maintain tight sealing at fluid/tip interface — important to avoid leaks when using heavy materials or under high pressure.
• Durable and heavy‑use ready: Built for demanding applications, repeated cycles, and exposure to coatings or foam chemicals.
• Easy replacement/maintenance: Simple to replace during gun maintenance or when switching to a large‑tip configuration, avoiding need for full gun overhaul.

Maintenance & Installation Guidelines

• Ensure all fluid passages and tip areas are clean and free from old material or debris before installing the packing tip.
• Install the packing tip carefully according to the spray/foam gun manual — avoid overtightening to prevent damage to the packing or threads.
• After installation, test the spray or foam flow with appropriate material (or solvent) to verify consistent flow and leak‑free operation before full use.
• Clean and flush the gun thoroughly after use — this helps preserve the packing tip, avoid build-up, and prolong its service life.
• Inspect packing tip periodically, especially if using heavy or abrasive coatings — replace immediately if there is wear, damage, or leak development.
