Wacker Neuson 5004102290 Plug R 1/2 With Magnet

The Wacker Neuson Plug R 1/2 With Magnet is a genuine OEM component designed for the RS800H Single Drum Vibratory Roller. As a direct factory part, it meets the exact material and dimensional standards set by Wacker Neuson for this application. Sourcing the correct plug with the integrated magnet is critical — this is not an interchangeable generic fitting. Confirm your model number before ordering to ensure a proper match.

Key Features

• Integrated Magnetic Element: — The built-in magnet actively captures ferrous metal particles suspended in fluid, helping keep internal systems clean and extending the service life of downstream components.
• Genuine OEM Construction: — Manufactured by Wacker Neuson to the exact material grade and thread specification for the R 1/2 port, ensuring a secure, leak-free seal from the first installation.
• Correct Thread Sizing: — The R 1/2 taper thread profile matches the original port geometry on the RS800H, seating properly without the risk of cross-threading or over-torquing that mismatched plugs can cause.
• RS800H Series Compatibility: — Verified fitment for the RS800H Single Drum Vibratory Roller, so you can order with confidence knowing this part belongs in your machine.
• Contamination Control: — A worn or missing magnetic plug allows metal debris to circulate through the system unchecked, accelerating wear on bearings, gears, and seals — this OEM replacement restores that protection immediately.

A magnetic drain or inspection plug serves two roles at once: it seals a threaded port in a fluid-filled housing — typically a gearbox, drum drive, or hydraulic sump — and uses an embedded magnet to attract and hold fine ferrous particles that circulate in the oil. Over time these particles are a byproduct of normal gear and bearing wear, and without a magnetic plug they remain in suspension, acting as an abrasive that accelerates internal damage. When the plug is removed for a fluid service interval, the collected debris on the magnet also gives a technician a useful visual indicator of how much wear is occurring inside the housing.
