Wacker Neuson 5000158906 Cap Pip 3/8 Tapered Plug

The Wacker Neuson is a genuine OEM Cap Pip 3/8 Tapered Plug designed for the CRT48-31V series ride-on concrete trowels, including the High Speed, standard, and Electronic Steering variants. As a direct OEM replacement, this plug is manufactured to the same specification as the original, ensuring a proper seal and correct fitment within the hydraulic or fluid circuit it serves. Wacker Neuson part covers the CRT48-31V-H, CRT48-31V-E, CRT48-31V-ES-E, and CRT48-31V-ES configurations, making it a versatile service part for operators running any variant of this 48-inch ride-on trowel platform. Keep this part on hand for planned maintenance or unscheduled repairs to get your trowel back in operation quickly.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to the original pressure and taper specification, this plug maintains a leak-free seal in the port it services — critical for preventing fluid loss in hydraulic or fuel circuits.
• Tapered 3/8 Thread Profile — The tapered pipe thread design creates a self-sealing mechanical connection as it's torqued into place, eliminating the need for additional sealant in most applications.
• Broad CRT48-31V Series Coverage — Fits the CRT48-31V-H High Speed, CRT48-31V-E, CRT48-31V-ES-E, and CRT48-31V-ES Electronic Steering ride-on trowel models from a single part number.
• Fluid System Protection — A correctly installed plug prevents contamination ingress and fluid weepage at open ports, protecting downstream components and keeping the trowel's operating systems at full capacity.
• Direct OEM Replacement — Sourced directly through Wacker Neuson's parts network, 5000158906 installs into the original port without thread chasing or fitting adaptation.

A tapered pipe plug seals an unused or service port in a fluid circuit — hydraulic, fuel, or coolant — by threading into the opening and compressing against the port walls as it tightens. On ride-on concrete trowels like the CRT48-31V series, these plugs are used throughout the hydraulic steering and drive systems to cap ports during assembly, service, or component replacement. A damaged, cross-threaded, or missing plug at any of these points can result in fluid weepage, air ingress, or pressure loss that affects steering response and drive performance. Replacing a worn or leaking plug promptly with the correct OEM part restores the integrity of the circuit and prevents further fluid-related issues.
