The Wacker Neuson Main Jet Nozzle is a genuine OEM component designed for the RD12A-90 series tandem rollers and the GS12Ai. Sourced directly from Wacker Neuson, this part meets the original engineering specifications for your machine — so you get the same spray pattern, flow rate, and fit as the part that left the factory. Compatible across the RD12A-90 Double Drum Roller, RD12A-90 Tandem Roller, RD12A-90 Tandem Roller with Foldable ROPS, and the GS12Ai, the is a straightforward drop-in swap with no guesswork on compatibility.
Key Features
- Calibrated Flow Output: — Manufactured to OEM specification, this jet nozzle delivers the correct water or fluid flow rate critical to effective drum wetting and compaction performance.
- Direct Drop-In Replacement: — Engineered to match the original nozzle's port size and thread specification, allowing installation without modification or adapter fittings.
- Broad RD12A-90 and GS12Ai Fitment: — Confirmed compatible with the RD12A-90 Double Drum Roller, RD12A-90 Tandem Roller, RD12A-90 Foldable ROPS variant, and the GS12Ai.
- Consistent Drum Coverage: — A functioning main jet nozzle ensures even moisture distribution across the drum surface, preventing asphalt or material from sticking and maintaining a clean compaction pass.
- Genuine Wacker Neuson OEM Part: — Carries the Wacker Neuson OEM designation, meaning it is the same component used in original machine assembly — not a reverse-engineered substitute.
The main jet nozzle controls the flow of water onto the roller drums during compaction operations. By keeping the drum surface evenly wetted, it prevents hot mix asphalt and other materials from adhering to the drums, which would otherwise cause surface defects and uneven compaction. When a jet nozzle becomes clogged, worn, or damaged, drum wetting becomes inconsistent or fails entirely — leading to material pickup, poor finish quality, and increased wear on the drum surface itself.
