The Wacker Neuson Seal Ring 15 X 20.5 X 7.5 is a genuine OEM component designed for the IRFU58, IRFU65, IREN57, IREN65, IRSEN, and IRFUN series internal concrete vibrators. Sourced directly from Wacker Neuson, this seal ring meets the exact material and dimensional standards of the original part — so you get a drop-in fit without guesswork. It is compatible across an extensive range of internal vibrator configurations, including standard, GV, CH, and UK variants at both 115V and 230V. If you're servicing a Wacker Neuson internal vibrator and need a sealing component you can count on, part is the correct replacement to have on hand.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original compound and hardness specifications, ensuring proper compression and fluid retention in high-frequency vibrator applications.
- Exact Dimensional Match — At 15 x 20.5 x 7.5 mm, this seal ring seats correctly in its housing bore without shimming or adjustment, maintaining the original sealing geometry.
- Broad Series Compatibility — Fits IRFU58, IRFU65, IREN57, IREN65, IRSEN, IRFUN, IRflex, and IRSE-FU series internal vibrators across a wide range of cord lengths, voltages, and regional variants.
- Protects Internal Components from Contamination — A correctly seated seal ring prevents moisture, concrete slurry, and debris from entering the vibrator housing, which directly protects the motor and drive components inside.
- Genuine Wacker Neuson OEM Part — Part number 5002003770 is an authorized Wacker Neuson replacement, carrying the same part number as the unit it replaces for straightforward parts-book verification.
A seal ring in a concrete internal vibrator creates a barrier between the working end of the tool and its internal mechanical and electrical components. In high-frequency vibrators like the Wacker Neuson IREN and IRFU series, this small seal carries a critical job: keeping concrete slurry and water out of the housing during immersion. When a seal ring wears, hardens, or takes on a set over time, its ability to compress and maintain a tight fit is reduced — allowing moisture ingress that can lead to premature motor failure or damage to the converter unit. Replacing a worn seal ring like the 5002003770 at the first sign of seepage is one of the most cost-effective preventive maintenance steps for internal vibrator service life.
