The Wacker Neuson Sealing Plug is a genuine OEM component designed for the IRFU, ARFU, and FUflex series internal concrete vibrators, covering a wide range of 120 V and 230 V models across the IRFU30, IRFU38, IRFU45, IRFU58, IRFU65, ARFU26, and FUflex4 lines. As a direct OEM part, it is manufactured to the same standards as the original component that left the factory, ensuring a correct fit within the vibrator housing. This plug is compatible with both standard and regional variants, including CH, GV, UK, and US configurations across the supported model range. If you are servicing any of the listed IRFU, IRSE, ARFU, or FUflex units, verifying part number against your machine's model number is the fastest way to confirm this is the right part.
Key Features
- Genuine OEM Sealing Integrity — Manufactured by Wacker Neuson to the original material and dimensional specification for this plug position, ensuring the housing cavity is properly closed and protected.
- Drop-In Housing Fit — Engineered to seat directly into the designated port on the vibrator body without reworking, trimming, or adapting the surrounding components.
- Broad Series Coverage — A single part number covers IRFU30, IRFU38, IRFU45, IRFU58, and IRFU65 variants alongside ARFU26, IRSE-FU, and FUflex4 models, spanning 120 V and 230 V configurations in standard, CH, GV, UK, and US versions.
- Maintains Housing Protection — A correctly seated sealing plug prevents moisture, concrete slurry, and debris from entering the vibrator housing — keeping internal components operating in a controlled environment.
- Electrical Safety Compliance — On electric internal vibrators, an intact and properly fitted plug is part of the moisture and ingress protection design; using the correct OEM part helps maintain the intended protection rating of the unit.
A sealing plug closes off an access or assembly port in the vibrator's housing — a small but critical component that keeps the internal cavity sealed against the wet, abrasive environment concrete work creates. If this plug is missing, cracked, or improperly seated, moisture and concrete slurry can work their way into the housing, leading to corrosion of internal parts and potential electrical faults in the drive circuitry. Replacing a damaged or absent sealing plug promptly is one of the simplest preventive maintenance steps for extending the service life of an internal electric vibrator.
