- SAE 3/8 Thread Standard — Threaded to the SAE 3/8 standard for a direct, tool-ready installation into the original port without thread adapters or modifications.
- Broad G-Series Compatibility — Fits a wide range of Wacker Neuson G-Series mobile generators from the G25 through the G230, covering skid-mounted, cold weather, extended run, and custom configurations.
- Leak-Free Fluid Port Sealing — A correctly seated plug prevents fluid loss and contamination entry at the service port, protecting the generator's fluid systems during operation and transport.
- Verified OEM Part Number — Ordering by part number 5000179122 confirms you are receiving the exact Wacker Neuson replacement plug specified for these generator models.
An SAE 3/8 plug seals an open threaded port in a fluid system — typically used to cap off a drain, fill, or service access point on the generator's engine or fluid circuit. It prevents fluid from leaking out and keeps contaminants from entering the system when the port is not in active use. A damaged, cracked, or missing plug can result in fluid loss, environmental contamination, and potential engine damage if left unaddressed during operation or transport.
