The Wacker Neuson is a genuine OEM Radiator Top Hose designed for RD27-100 and RD27-120 Hydrostatic Vibratory Rollers. As a direct OEM replacement, part is manufactured to the exact dimensions and material specifications required by these tandem roller models, ensuring a secure, leak-free connection between the engine and radiator. Compatible across multiple RD27 configurations including the,, and machine variants, this hose is the correct choice when restoring your cooling system to full operating condition. Sourcing a genuine Wacker Neuson part ensures your roller stays matched to the original engineering intent for that model family.
Key Features
- OEM-Grade Hose Construction — Manufactured to the original pressure rating and temperature tolerance required for the RD27 cooling circuit, not a generic hose cut to size.
- Direct Routing Match — Molded to the correct routing profile for the RD27-100 and RD27-120, so the hose seats properly at both the radiator neck and engine coolant outlet without stretching or kinking.
- Broad RD27 Family Coverage — Confirmed fitment across RD27-100 and RD27-120 Hydrostatic Vibratory Roller variants, covering a wide range of machine serial configurations.
- Cooling System Integrity — A correctly fitted top hose maintains proper coolant flow and system pressure; a cracked or swollen hose risks overheating the roller's engine mid-shift.
- Genuine Wacker Neuson OEM Part — Backed by Wacker Neuson's parts program, ensuring the part number, material spec, and fitment data match the original component exactly.
The radiator top hose carries hot coolant from the engine's thermostat housing to the top inlet of the radiator, where the cooling process begins. It is a critical link in the closed-loop cooling system that keeps the engine operating within its safe temperature range during compaction work. When this hose cracks, softens, or loses its seal at either end, coolant loss can occur rapidly, leading to engine overtemperature and unplanned machine downtime on the job.
