The Wacker Neuson Plug Cap is a genuine OEM component designed for DPU6555Heh, DPU6555Hech, DPU5545Heh, DPU5260Hehb+, and DPU6275Hehb+ series vibratory plate compactors sold in the US market. Sourced directly from Wacker Neuson, this is the same plug cap fitted at the factory — ensuring a correct, exact match to the original part. Genuine OEM designation means no guesswork on compatibility: part number is verified against each listed model's parts documentation. If your compactor's plug cap is cracked, loose, or missing, this is the authorized replacement to restore the machine to proper working condition.
Key Features
- Genuine OEM Ignition Circuit Integrity — Manufactured to Wacker Neuson's original electrical specification, ensuring the correct dielectric properties and secure fit on the spark plug terminal.
- Direct Plug-and-Play Installation — Snaps directly onto the spark plug in place of the original cap with no modification to wiring or the ignition lead.
- Broad DPU Series Coverage — Compatible with DPU6555Heh, DPU6555Hech, DPU5545Heh, DPU5260Hehb+, and DPU6275Hehb+ US-market models under a single part number.
- Reliable Ignition Spark Delivery — A correctly seated plug cap maintains a clean, uninterrupted spark signal; a damaged or missing cap can cause misfires, hard starting, or failure to run under load.
- Electrical Safety Compliance — The plug cap provides insulation between the high-voltage ignition lead and the engine casing, reducing the risk of unintended discharge during operation and servicing.
The plug cap sits at the top of the spark plug and connects the high-tension ignition lead to the plug's terminal, channeling the high-voltage spark needed to ignite the fuel-air mixture in the engine. It also acts as an electrical insulator, protecting the operator and surrounding components from stray ignition voltage. When the plug cap deteriorates — through cracking, a loose fit, or internal corrosion — the ignition signal weakens or shorts to ground, typically resulting in hard starting, misfiring, or a complete no-start condition that stops work on the compactor entirely.
