The Wacker Neuson is a genuine OEM Hose Assembly 3/8 To 1/4 Reducer designed for the RD12A-90 Tandem Roller and CRT36 Ride-On Trowel series. Sourced directly from Wacker Neuson, this assembly carries the full backing of an authorized OEM component — built to the exact configuration the machine was engineered around. Compatibility spans multiple configurations across the RD12A-90 and CRT36-24A, CRT36-25, and CRT36-26A model lines, making part number a dependable choice across a broad range of Wacker Neuson equipment in your fleet.
Key Features
- OEM-Correct Flow Transition: — Manufactured to Wacker Neuson's specified bore reduction from 3/8 in. to 1/4 in., ensuring the hydraulic or fluid circuit maintains the intended flow rate and pressure balance.
- Direct-Fit Assembly: — Connects to existing ports and fittings on the RD12A-90 and CRT36 series without rework, matching the original routing path and end connections.
- Broad Model Coverage: — Fits RD12A-90 Tandem Rollers (including Foldable ROPS variants) and CRT36-24A, CRT36-25, and CRT36-26A Ride-On Trowels across multiple build configurations.
- Sustained System Integrity: — A correctly functioning reducer hose assembly maintains stable fluid delivery between mismatched line sizes; a failed or leaking assembly can cause pressure loss, erratic machine response, or fluid contamination.
- Genuine Wacker Neuson Part: — Supplied as an authentic OEM component, verified against part number 5000193171, so you receive exactly what the machine left the factory with.
A reducer hose assembly bridges two hydraulic or fluid lines of different diameters — in this case stepping down from a 3/8 in. line to a 1/4 in. line — while maintaining a sealed, leak-free connection between them. This transition is critical in managing flow velocity and pressure within the circuit; an improperly sized or deteriorated reducer can introduce pressure drops, cavitation, or fluid bypass that disrupts the performance of downstream components. When this assembly cracks, softens, or develops a leak, the affected circuit loses efficiency and the machine may exhibit sluggish response or visible fluid loss, making prompt replacement essential to keeping the system operating as designed.
