Wacker Neuson 0079235 Water Tank Cap

The Wacker Neuson Water Tank Cap is a genuine OEM Water Tank Cap designed for a wide range of Wacker Neuson CRT36 and CRT48 ride-on concrete trowels, RD7 and RD11 tandem rollers, LTN6 and LTN8 light towers, and WP and VP series vibratory plates. Sourced directly from Wacker Neuson, part number (also cataloged as ) meets the original equipment specification for a secure, leak-free seal on the water tank. This cap fits across an extensive lineup of Wacker Neuson machines, making it a practical stock item for fleet operators and service technicians who maintain multiple equipment types. Confirm your model number against the fitment list before ordering to ensure a correct match.

Key Features

• Genuine OEM Seal Integrity — Manufactured to Wacker Neuson's original specification, this cap forms the same compression seal as the factory-installed part, preventing water loss or contamination at the tank opening.
• Direct Drop-In Replacement — Threaded to the original tank neck dimensions, the 0079235 installs without modification, restoring the tank closure on your machine quickly.
• Broad Cross-Family Fitment — Compatible with CRT36 and CRT48 ride-on trowels, RD7 and RD11 tandem rollers, LTN6L, LTN6C, and LTN8K light towers, and multiple WP and VP vibratory plate models.
• Protects Water System Performance — A properly sealing tank cap keeps the water supply pressurized and uncontaminated, ensuring consistent water delivery to the systems that depend on it — whether for trowel cooling, roller drum wetting, or other machine functions.
• Dual Part Number Reference — Listed under both 0079235 and 5000079235; either number references the same genuine Wacker Neuson component, making cross-referencing against service manuals and parts diagrams straightforward.

The water tank cap seals the opening of the onboard water tank, maintaining a closed system that prevents leaks, spills, and contamination during operation and transport. On machines such as ride-on trowels and tandem rollers, a reliable tank seal ensures the water supply remains available for drum wetting or surface conditioning throughout the work cycle. A cracked, stripped, or missing cap can lead to water loss, debris ingestion into the tank, and inconsistent performance from water-dependent systems — making this a small but critical service component worth keeping on hand.
