Wacker Neuson 5002003772 Seal Ring 17 X 26 X 0.8 Pg21

The Wacker Neuson Seal Ring 17 X 26 X 0.8 Pg21 is a genuine OEM component designed for the IREN series internal vibrators, covering the IREN 30, IREN 38, IREN 45, IREN 57, IREN 57k, IREN 58, IREN 65, and IREN 65k model families. As a direct Wacker Neuson OEM part, the is manufactured to the exact material grade and dimensional tolerances specified for these vibrators, ensuring a proper seal at the PG21 cable entry point. This seal ring is a critical service component across the full IREN lineup, including standard, GV, ST, and extended-hose variants. Keep a spare on hand to avoid unnecessary downtime during concrete placement operations.

Key Features

• OEM-Grade Elastomer Construction — Manufactured to Wacker Neuson's specified material grade, delivering the compression and chemical resistance required at the PG21 cable entry interface on IREN internal vibrators.
• Exact Dimensional Match — At 17 x 26 x 0.8 mm, this seal ring drops into the PG21 fitting on IREN vibrator housings without modification, restoring the original sealing geometry.
• Broad IREN Series Coverage — A single part number covers the IREN 30, 38, 45, 57, 57k, 58, 65, and 65k families across standard, GV, ST, and extended-hose (6m, 8m, 10m) configurations.
• Maintains Vibrator IP Protection — A correctly seated seal ring preserves the ingress protection rating at the cable entry point, keeping moisture and concrete slurry out of the vibrator head during use.
• Sourced Direct from Wacker Neuson — Genuine OEM traceability means the part number, material spec, and geometry are verified against the original production standard for these vibrators.

A seal ring at the PG21 cable entry is responsible for creating a watertight barrier where the power cable enters the vibrator head housing. In internal concrete vibrators, this junction is continuously exposed to water, cement slurry, and mechanical vibration — conditions that gradually degrade the seal material. When the ring becomes compressed, cracked, or hardened with age, moisture can penetrate the housing, leading to electrical faults or damage to internal components. Replacing the seal ring at each major service interval is a straightforward step that protects the integrity of the vibrator and keeps it operating safely in wet concrete environments.
