Wacker Neuson 5000183432 Cap Overflow Bottle Gasket

The Wacker Neuson Cap Overflow Bottle Gasket is a genuine OEM component designed for a broad range of Wacker Neuson equipment including CRT48 ride-on trowels, LTN6 and LTW light towers, G-series mobile generators, and RD27 vibratory rollers. As a factory-authorized part, it delivers the exact material grade and dimensional profile required to maintain a proper seal at the overflow bottle cap. This gasket is a direct OEM replacement sourced through Wacker Neuson's authorized parts channel, ensuring it meets the same standards as the part originally installed at the factory. Confirm fitment using part number against your machine's serial number and model designation before ordering.

Key Features

• OEM Sealing Material — Manufactured to the precise compression and material specification required for the overflow bottle cap, ensuring consistent sealing performance across temperature cycles.
• Drop-In Cap Replacement — Designed to seat directly onto the overflow bottle cap interface without trimming or reworking, retaining the original cap hardware and bottle assembly.
• Broad Wacker Neuson Fitment — Compatible with CRT48 ride-on trowels, LTN6 and LTW light tower families, G50 through G320 mobile generators, and RD27-100/RD27-120 vibratory rollers.
• Prevents Coolant Seepage — A failed or compressed overflow bottle gasket allows coolant vapor and fluid to escape the overflow system, leading to low coolant levels and potential overheating; this replacement restores proper containment.
• Genuine OEM Part — Sourced directly from Wacker Neuson, part number 5000183432 carries the full backing of the OEM parts program for traceability and fitment confidence.

The overflow bottle cap gasket forms the primary seal between the cap and the coolant overflow reservoir, preventing coolant loss through the cap opening during normal pressure cycling of the cooling system. When the engine heats up and coolant expands, this gasket ensures that displaced fluid is directed into the overflow bottle rather than escaping as vapor or liquid. A worn, cracked, or flattened gasket breaks that seal, allowing coolant to escape — which can result in unexplained coolant loss, overheating warnings, and residue buildup around the overflow bottle that indicates a slow leak.
