The Wacker Neuson Screw Connection M20x1,5 is a genuine OEM component designed for the IRFU, IRSE-FU, FUflex, ARFU, and IEC series internal concrete vibrators. Sourced directly from Wacker Neuson, this part meets the exact dimensional and material specifications of the original, ensuring a correct and secure fit at the connection point. It is compatible across a broad range of models including IRFU30, IRFU38, IRFU45, IRFU58, and IRFU65 variants in both 230V and 120V configurations, as well as IRSE-FU and ARFU converter-equipped units. Keeping this connection fitting in good condition is essential to maintaining the integrity of the vibrator assembly during operation.
Key Features
- Genuine OEM Thread Integrity — Manufactured to Wacker Neuson's exact M20x1.5 thread specification, ensuring full engagement and a leak-free, play-free connection at the vibrator housing interface.
- Direct Bolt-In Replacement — Threads directly into the original port using the M20x1.5 fine-thread pitch — no re-tapping, adapters, or rework needed at installation.
- Broad Series Compatibility — Fits IRFU, IRSE-FU, FUflex4, ARFU, and IEC series internal vibrators across 30mm, 38mm, 45mm, 58mm, and 65mm head diameters in both 230V and 120V variants.
- Maintains Vibrator Output Consistency — A correctly seated screw connection keeps the internal vibrator assembly properly sealed and aligned, preserving the full compaction force delivered to the concrete.
- Electrical Safety Compliance — As a structural connection component on high-frequency electrical vibrator equipment, using the correct OEM fitting helps maintain the enclosure rating and safe operation of the converter unit.
A screw connection on a concrete internal vibrator serves as a threaded coupling that joins sections of the vibrator assembly — typically linking the flexible drive shaft housing, vibrator head, or converter connection — and keeps the unit mechanically secure during use. If this fitting becomes damaged, cross-threaded, or worn, the joint can loosen under the high-frequency vibration loads the equipment generates, leading to misalignment, moisture ingress, or complete separation of the assembly. Replacing a failed or degraded screw connection with the correct OEM part restores the structural integrity of the vibrator and ensures the machine performs safely and consistently on the job.
