The Wacker Neuson Plug Cap is a genuine OEM component designed for DPU80Lec, DPU90Lec, and DPU110Lec series reversible and standard plate compactors. Sourced directly from Wacker Neuson, this plug cap matches the exact specification of the original part — ensuring a correct, secure installation with no guesswork. Compatible across a wide range of DPU series models including the DPU80Lec670, DPU90Lec770 US, DPU110Lec970, and DPU110Lekc970, among others.
Key Features
- Genuine OEM Electrical Integrity — Manufactured to Wacker Neuson's original specification, ensuring the plug cap delivers the correct insulation properties and secure contact protection for the ignition circuit.
- Direct-Fit Replacement — Engineered to seat and connect exactly as the original, allowing straightforward swaps on compatible DPU series plate compactors without additional hardware.
- Broad DPU Series Compatibility — Fits a wide range of Wacker Neuson DPU80Lec, DPU90Lec, and DPU110Lec models in both standard and reversible configurations, including US-spec variants.
- Ignition Circuit Protection — A properly seated plug cap maintains a reliable electrical connection to the spark plug, preventing misfires, rough running, and hard-start conditions that a worn or damaged cap can cause.
- Electrical Safety Assurance — The plug cap insulates the high-voltage ignition lead from the plug terminal, reducing the risk of arcing or shock hazard during operation and routine maintenance.
The plug cap fits over the spark plug terminal and connects the high-tension ignition lead to the plug itself, completing the ignition circuit that fires the engine. It provides both a secure electrical connection and an insulating barrier that protects against voltage leakage and arcing. When a plug cap cracks, loosens, or deteriorates internally, the result is a weak or intermittent spark — leading to poor engine starts, loss of power, or a compactor that won't run at all.
