Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and thread specifications, ensuring a leak-free, pressure-rated seal consistent with the original plug.
- Direct-Fit Replacement — Threaded to match the original port dimensions on RD7 tandem rollers and DPU-series reversible vibratory plates, dropping straight into the existing bore without reworking.
- Broad DPU Series Coverage — Fits DPU 4045H, DPU 4545H, DPU 5045H, DPU 5545H, and DPU 6555H reversible vibratory plate compactors across a wide range of configurations and regional variants.
- RD7 Tandem Roller Compatibility — Compatible with RD7H, RD7He, RD7Hf, RD7Heh, RD7Hfb, and RD7Hehfb walk-behind double-drum roller variants, including EU and North America editions.
- Prevents Fluid Loss and Contamination — A correctly seated screw plug keeps hydraulic or lubricating fluid contained and contaminants out; a damaged or missing plug can lead to rapid fluid loss and accelerated internal wear.
A screw plug is a threaded closure used to seal an access port, drain point, or unused fluid passage within a machine's hydraulic, lubrication, or gearbox system. It holds internal fluids in place and keeps dirt, moisture, and debris out of precision internal components. When a screw plug is missing, cross-threaded, or cracked, fluid can escape and external contaminants can enter, leading to accelerated wear, overheating, or system failure. Replacing a damaged plug promptly with the correct OEM part preserves the fluid system's integrity and keeps the machine running within its designed operating parameters.
