Wacker Neuson 5000172971 Plug 1/8 Square Head Plated

The Wacker Neuson Plug 1/8 Square Head Plated is a genuine OEM component designed for the CRT36 and CRT48 series ride-on concrete power trowels. Sourced directly from Wacker Neuson, this plug meets the original equipment specification for proper sealing and fit within the machine's fluid or hydraulic circuit. It is compatible across a wide range of CRT models, including the CRT36-24A, CRT36-25, CRT36-26A, CRT48-31V, CRT48-33K, CRT48-34V, CRT48-35L, CRT48-35V, CRT48-37V, CRT48-57K, and their Power Steer and Dual-Fuel variants. As a genuine OEM part, the delivers the correct thread specification, plating, and material grade that Wacker Neuson's engineers specified for these machines.

Key Features

• Correct Thread Sealing Spec — Genuine OEM plating and 1/8 square head geometry ensure a leak-free, metal-to-metal seal at the port without the guesswork of aftermarket sizing variations.
• Direct Port Fit — The square head drive pattern installs cleanly into the designated port on CRT36 and CRT48 series trowels, engaging with standard tooling for fast, confident installation.
• Broad CRT Series Coverage — A single part number covers an extensive range of CRT36 and CRT48 configurations, including Power Steer, Dual-Fuel, EU-spec, and Wheel Kit variants.
• Fluid System Integrity — A correctly seated plug maintains pressure and prevents fluid contamination in the trowel's circuit; a failed or missing plug can result in fluid loss, pressure drop, and unplanned service time.
• Genuine Wacker Neuson OEM Part — Manufactured to the same standard as the original component, ensuring dimensional accuracy and corrosion resistance from the plated finish.

A pipe plug serves as a sealing fastener used to close off unused or access ports in a machine's fluid, hydraulic, or oil circuit. On Wacker Neuson CRT ride-on trowels, these ports appear throughout the engine, hydraulic, and gearbox assemblies, and the plug prevents fluid from escaping or contaminants from entering the system. When a plug corrodes, strips, or is lost during service, the affected port is left open to leakage or ingestion of debris — either of which can accelerate wear on nearby components or cause a more serious fluid-system failure. Replacing a damaged or missing plug promptly with the correct OEM part keeps the machine's fluid circuits sealed and operating as intended.
