Wacker Neuson 108093 Spark Plug Terminal Cap

The Wacker Neuson 108093 Spark Plug Terminal Cap is a genuine OEM component designed for a wide range of Wacker Neuson PT2A trash pumps, BPU2540A reversible plate compactors, VP and WP single-direction vibratory plate compactors, and BPS plate compactors. As a direct OEM replacement, the 108093 is manufactured to the exact specifications required by these machines, ensuring a secure, consistent connection every time. This cap fits an extensive lineup including the PT2A, PT2A(I), VP1340A, VP1550A, VP2050A, WP1540A, WP1550A, BPS1550A, BPS2050A, and BPU2540A series, among others. Keep a spare on hand to avoid extended downtime during routine ignition maintenance.

Key Features

• Genuine OEM Ignition Integrity — Manufactured to Wacker Neuson's exact dielectric and contact specifications, maintaining consistent spark energy transfer at the plug terminal.
• Broad Cross-Family Compatibility — A single part number covers PT2A trash pumps, BPU2540A reversible plates, VP/WP single-direction vibratory plates, and BPS compactors — consolidating your spare parts inventory.
• Direct Connector Fit — Snaps onto the spark plug terminal as the factory original did, with no rework to the ignition lead or boot required.
• Protects Ignition System Performance — A worn or cracked terminal cap allows moisture ingress and causes voltage leakage, leading to misfires, hard starts, and erratic engine behavior; a fresh cap restores clean, reliable ignition.
• Electrical Safety at the Ignition Point — The cap provides the insulating barrier between the high-voltage ignition lead and the plug terminal, keeping the electrical path contained and reducing the risk of inadvertent arc or shock during servicing.

The spark plug terminal cap sits at the connection point between the ignition wire and the spark plug itself, forming a secure, insulated coupler that channels high-voltage current directly into the plug's terminal post. It keeps moisture, dirt, and vibration from disrupting that connection — all of which are constant factors on compaction and pumping equipment used in the field. When the cap cracks, loosens, or degrades internally, voltage can arc away from the plug rather than firing the combustion charge, resulting in hard starts, engine misfires, or a complete no-start condition. Replacing the 108093 Spark Plug Terminal Cap restores the integrity of the ignition circuit and gets the engine firing cleanly again.
