The Wacker Neuson Lock Plug is a genuine OEM component designed for the TH627 series. Sourced directly from Wacker Neuson, this part meets the original design and material specifications used during factory assembly. It installs in place of the original without adaptation, ensuring a secure, properly sealed connection. Verify your model and machine number against the TH627 (418-02) parts list before ordering to confirm compatibility.
Key Features
- Genuine OEM Material Integrity — Manufactured to the same material and dimensional tolerances as the original, ensuring the plug seats and locks correctly without leakage or loosening.
- Direct Drop-In Replacement — Designed to fit the TH627 mounting point exactly, with no reworking of the surrounding assembly required.
- TH627 Series Fitment — Confirmed fitment for the Wacker Neuson TH627 (418-02) per the official spare parts list.
- Secure Closure Performance — A correctly functioning lock plug maintains a sealed, retained connection in its circuit or port; a worn or missing plug can result in fluid loss, contamination ingress, or component disconnection during operation.
- Fluid and Contamination Control — Where used in hydraulic, fuel, or fluid-circuit applications, the lock plug prevents unintended discharge and protects internal components from external debris — making correct part selection a safety-relevant choice.
A lock plug is a small but critical sealing and retention component used to close off a port, bore, or fitting within a machine's fluid or electrical system. It prevents the escape of fluid or the ingress of contaminants, and its locking feature ensures it remains positively retained under vibration or pressure cycles. When a lock plug fails, cracks, or goes missing, the result can range from minor fluid seepage to loss of system pressure or open exposure of a sensitive internal passage — all of which affect machine reliability and operator safety.
