Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional standards, ensuring the hose maintains proper flow rate and pressure integrity within the water system circuit.
- Direct-Fit Replacement — Designed to connect to the existing water system fittings on RD7 series rollers without modification, allowing for a straightforward swap during routine service or breakdown repair.
- Broad RD7 Series Compatibility — Confirmed fitment across RD7, RD7A, RD7H, RD7He, and RD7Ye tandem roller models, covering both standard and walk-behind roller configurations.
- Sustained Drum Wetting Performance — A correctly functioning water hose delivers consistent flow to the drum wetting system, preventing asphalt pickup on the drums during compaction passes and protecting surface finish quality.
The water hose on an RD7 series tandem roller is part of the drum wetting system, which delivers a continuous supply of water to the compaction drums during asphalt rolling operations. Keeping the drums wet prevents hot asphalt from adhering to the drum surface, which would otherwise cause tearing and surface defects in the mat. A cracked, kinked, or deteriorated water hose reduces flow to the drums, leading to material buildup and potential damage to the finished surface — making timely replacement essential to maintaining compaction quality and protecting the asphalt mat.
