Wacker Neuson 5002003792 Seal Ring 9 X 13.5 X 5.5

The Wacker Neuson Seal Ring 9 X 13.5 X 5.5 is a genuine OEM component designed for the IRFU, IREN, IRSEN, IRFUN, IRSE-FU, and IRflex series internal concrete vibrators. Sourced directly from Wacker Neuson, this seal ring meets the exact dimensional and material specifications required for proper fit and long-term sealing performance across a wide range of 38 mm and 45 mm vibrator heads. Compatible models span multiple voltage configurations including 42 V, 115 V, 120 V, 230 V, and 250 V variants, covering both standard and GV rubber-tip configurations. Confirm your model number against the fitment list before ordering to ensure correct application.

Key Features

• Dimensionally Exact Sealing — Manufactured to the precise 9 x 13.5 x 5.5 mm specification, ensuring correct compression and a leak-free interface at the vibrator head assembly.
• Genuine OEM Part — Supplied by Wacker Neuson as part number 5002003792, this is the same seal ring installed at the factory — no substitution or adaptation needed.
• Broad Vibrator Series Coverage — Fits IRFU, IREN, IRSEN, IRFUN, IRSE-FU, and IRflex internal vibrators in both 38 mm and 45 mm head diameters, across a wide range of cord lengths and voltage configurations.
• Protects Internal Components — A correctly functioning seal ring keeps moisture, concrete slurry, and debris out of the vibrator head, preventing premature wear to bearings and motor windings.
• Direct Drop-In Service Part — Designed for straightforward replacement during scheduled maintenance or after seal wear is detected, restoring the vibrator head to its original sealing integrity.

A seal ring in a concrete internal vibrator creates a barrier between the vibrator head's internal working components and the surrounding environment — including water, cement paste, and aggregate fines. During operation, the head is submerged repeatedly in wet concrete, placing constant demand on the seal to prevent ingress. When this seal ring wears, degrades, or is damaged, moisture and slurry can penetrate the head housing, leading to bearing corrosion, electrical faults, and ultimately vibrator head failure. Replacing the seal ring at the first sign of wear is one of the most cost-effective ways to extend the service life of a vibrator head.
