Product Overview
The 15G284 Packing, Vee is a high-performance seal component designed for airless sprayer systems rated at 4 GPM. It’s engineered to provide a tight, wear-resistant seal in the pump packing area, enhancing fluid containment and extending maintenance intervals under rigorous use.
Key Features
| Part Number | 15G284 |
| Seal Type | Vee-packing seal for pump rod / cylinder interface |
| Flow Band | 4 GPM rating |
| Materials | Wear-resistant polymer blend, designed for abrasive coatings |
Materials & Performance
Constructed from a durable polymer compound, the 15G284 vee-packing offers excellent abrasion resistance and low friction movement around the pump rod. By maintaining rod alignment and minimizing leakage, it improves consistency in coating application and reduces downtime for replacements.
Installation & Maintenance
- Clean the packing bore and rod thoroughly before installation to avoid embedding particles that can accelerate wear.
- Insert the vee‐packing carefully, ensuring proper orientation of the lips and seating against the packing gland.
- During service intervals inspect the packing for signs of abrasion, extrusion or leaks and replace if wear is evident.
- Use adequate lubrication or fluid compatibility checks as per system manufacturer guidelines to optimise service life.
Applications
This part is ideal for professional airless coating systems used in industrial, manufacturing and large-scale finishing operations. Wherever fluid integrity, minimal spray interruption and long maintenance intervals are required, the 15G284 vee‐packing supports reliable system performance.
Frequently Asked Questions
A vee-packing seal uses a V-shaped cross-section that allows the seal lips to adapt to the rod movement and pressure fluctuations, maintaining tight contact and reducing leakage, especially under high cycle or abrasive conditions.
Replace the vee-packing when you observe increased fluid bypass, rod vibration, seal lip wear, extrusion of the packing, or reduced pump efficiency. Regular inspection during service cycles helps maintain optimal performance.
While generic packings may fit physically, the 15G284 is engineered to match exact specifications of the original system, including material, dimensional tolerances and performance. Using non-specified packings may reduce service life or compromise sealing reliability.
