The Wacker Neuson Grommet is a genuine OEM component designed for a broad range of Wacker Neuson equipment including CT36BDT walk-behind trowels, PT2B centrifugal trash pumps, PD3B and PDT2B diaphragm pumps, and B 3000 and B 5000 gasoline power units for internal vibrators. Sourced directly from Wacker Neuson, this Grommet matches the original part specification exactly, ensuring a correct fit with no guesswork at installation. As a genuine OEM part, it delivers the same material grade and dimensional accuracy as the grommet installed at the factory, giving you confidence that the repair is done right the first time.
Key Features
- OEM Material Integrity — Manufactured to Wacker Neuson's original compound and durometer specification, so the grommet maintains its sealing and cushioning properties under the vibration and heat cycles these machines generate.
- Drop-In Installation — Matches the original bore diameter and flange profile exactly, seating cleanly into the existing opening without trimming or modification.
- Wide Fitment Coverage — A single part number covers the CT36BDT walk-behind trowel, PT2B trash pump, PD3B and PDT2B diaphragm pumps, and B 3000 and B 5000 gasoline power units, making it a practical stock item across multiple machines on the same crew.
- Protects Wiring and Hoses from Abrasion — Cushions cables or lines passing through metal panels, preventing chafing that leads to electrical faults or fluid leaks over time.
- Genuine OEM Assurance — Supplied under Wacker Neuson part number 5000020516, so you can verify authenticity against your machine's parts manual before ordering.
A grommet is a small ring or collar, typically made from rubber or a flexible polymer, that is pressed into a hole in a metal panel or housing. Its primary job is to protect cables, wires, or hoses from the sharp edges of the opening — without it, vibration and movement cause the covering to chafe through, creating electrical shorts or fluid leaks. On high-vibration equipment like concrete trowels, trash pumps, and internal vibrator power units, grommets also act as a mechanical buffer, absorbing cyclic stress so the surrounding panel material does not fatigue and crack around the opening. A hardened, cracked, or missing grommet is a common source of wiring faults and fluid contamination that can be difficult to trace until significant damage has already occurred.
