The Wacker Neuson Sprinkler Pipe is a genuine OEM sprinkler pipe designed for the RD40-130 and RD45-140 series tandem rollers. As a direct OEM replacement, this part is sourced from Wacker Neuson and built to the exact specifications of the original component — ensuring a correct, trouble-free installation without guesswork. Fitment covers a wide range of RD40-130 and RD45-140 variants, including standard, offset drum (O), DPF-equipped, and US-market configurations. Using the correct OEM part keeps the drum wetting system operating as intended, protecting both the drum surface and the material being compacted.
Key Features
- OEM-Matched Flow Geometry — Manufactured to the original bore diameter and outlet pattern, ensuring consistent water distribution across the drum surface without adjustment.
- Direct-Fit Replacement — Engineered to connect directly to the existing sprinkler system plumbing on RD40-130 and RD45-140 rollers, using the same mounting points as the original pipe.
- Broad RD Series Compatibility — Fits standard, offset drum, DPF, and US-market variants across both the RD40-130 and RD45-140 tandem roller families.
- Protects Drum Surface and Mix Integrity — A functioning sprinkler pipe keeps asphalt from sticking to the drum; a cracked or blocked pipe leads to uneven wetting, material buildup, and surface defects in the finished mat.
- Genuine Wacker Neuson Part — Supplied as an authentic OEM component, verified against part number 5100012299, so you receive the correct part the first time.
The sprinkler pipe is part of the drum wetting system on a tandem roller, delivering a controlled flow of water across the face of the compaction drum. This water film prevents hot asphalt from bonding to the steel drum surface during paving and compaction passes. When the sprinkler pipe becomes cracked, clogged, or broken, water distribution becomes uneven or stops entirely — leading to asphalt sticking to the drum, surface tearing, and a compromised final finish that can require rework.
