Wacker Neuson 5200015830 Spray Bar — Genuine OEM for RD7 Series Tandem Rollers

The Wacker Neuson Spray Bar is a genuine OEM component designed for the RD7A, RD7H, RD7He, and RD7Ye series tandem and walk-behind rollers. As a factory-sourced part, it meets the exact design and material specifications of the original, ensuring correct installation without guesswork. This Spray Bar is a direct-fit replacement that restores proper drum wetting performance across the full range of compatible RD7 roller models. Keep your compaction operation running at full efficiency by replacing a worn or damaged spray bar with the correct OEM part.

Key Features

• OEM-Grade Water Distribution Integrity — Manufactured to the same flow and spray pattern specifications as the original, ensuring even drum wetting coverage with no hot spots or dry zones across the drum surface.
• Drop-In Installation — Engineered to match the original mounting points and connection geometry on RD7 series rollers, so the bar seats and secures exactly as the factory part did.
• Broad RD7 Series Coverage — Compatible with RD7A, RD7H, RD7He, and RD7Ye models across multiple tandem roller and walk-behind roller configurations, covering a wide range of serial number ranges.
• Protects Asphalt from Drum Pickup — A correctly functioning Spray Bar keeps the steel drums consistently wetted, preventing hot asphalt from sticking to the drum surface and compromising the finished mat quality.
• Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM parts network under part number 5200015830, so you get full confidence in origin, quality, and long-term durability.

The Spray Bar is mounted across the width of the roller drum and delivers a controlled mist of water to keep the drum surface wetted during asphalt compaction passes. This prevents the hot mix from adhering to the drum, which would otherwise cause tearing, surface defects, and uneven compaction. When the spray bar becomes clogged, cracked, or fails to distribute water evenly, drum pickup becomes a real risk — making timely replacement critical to protecting both the mat finish and the machine.
