The Wacker Neuson Lower Tube is a genuine OEM component designed for the IRFU45, IREN45, IRSEN45, IRSE-FU45, and IRflex45 series internal concrete vibrators. As a direct OEM part, is manufactured to the exact specifications required by Wacker Neuson, ensuring a proper fit across the full range of compatible 45mm vibrator heads. This Lower Tube is confirmed to fit an extensive range of models including IRFU45/230/5, IRFU45/120/5 US, IREN45/042/5, IREN45/250/5, IRflex45/230/5, and many additional variants within these families. Order with confidence knowing this is the same part supplied through Wacker Neuson's authorized parts network.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's exact dimensional tolerances for the 45mm vibrator head assembly, ensuring structural integrity under continuous high-frequency vibration loads.
- Direct Drop-In Replacement: — Engineered to connect directly to the vibrator head and flexible shaft assembly without modification, restoring the original vibration transfer path.
- Broad Series Compatibility: — Fits IRFU45, IREN45, IRSEN45, IRSE-FU45, and IRflex45 internal vibrator families across multiple voltage and cable-length configurations.
- Protects Vibration Output Integrity: — A worn or damaged lower tube disrupts the eccentric weight's rotation and reduces effective consolidation force delivered to the concrete pour.
- Verified OEM Part Number: — Cross-referenced against Wacker Neuson parts documentation; 5100006185 is the current-production replacement tube for this vibrator family.
The lower tube is the outermost housing at the working end of an internal concrete vibrator, enclosing the eccentric weight and bearing assembly that generate the high-frequency vibration used to consolidate fresh concrete. It is subjected to continuous rotational stress, abrasion from concrete aggregate, and immersion in a highly alkaline environment during every pour. When the lower tube becomes cracked, worn, or bent, it can allow moisture ingress that damages internal bearings, reduce vibration amplitude, or cause complete head failure — all of which compromise concrete consolidation quality and halt production until the assembly is repaired.
