The Wacker Neuson 5100048602 is a genuine OEM Vent Rollover Fitting, 3/4 NPT, 1/2 Barb designed for the G100, G130, G180, G230, and G320 series portable generators, including Tier 4 Final and Transport Canada configured units. As a direct OEM replacement, 5100048602 is manufactured to Wacker Neuson's original specifications, ensuring correct thread engagement on the 3/4 NPT port and a secure barb connection on the 1/2-inch fuel line. This fitting is purpose-built to handle the venting demands of mobile generator fuel systems, giving you confidence in a component that plays a direct role in fuel system integrity and safe operation.
Key Features
- Genuine OEM Fuel System Integrity — Manufactured to Wacker Neuson's original thread and barb specifications, ensuring a leak-free seal at both the 3/4 NPT port and the 1/2-inch barb connection.
- Rollover Vent Protection — Engineered to prevent fuel spillage if the generator is tilted or overturned, a critical function for safe transport and storage of mobile power equipment.
- Dual-Connection Design — The 3/4 NPT male thread seats directly into the fuel tank port while the 1/2-inch barb accepts the vent hose, allowing straightforward reinstallation with standard hand tools.
- Broad Generator Fitment — Compatible across the G100, G130, G180, G230, and G320 mobile generator families, including custom Tier 4 Final and Transport Canada configurations.
- Fuel System Safety Compliance — As a rollover vent fitting, correct specification matters for regulatory and operational safety; using the OEM part maintains the fuel system's original spill-prevention design.
A rollover vent fitting is a one-way valve installed in the fuel tank that allows pressure to equalize during normal operation while sealing automatically if the tank is tipped or inverted. This prevents raw fuel from escaping through the vent line during transport or an unexpected tip, protecting both the operator and the work environment. When this fitting cracks, corrodes, or loses its sealing function, fuel vapors can escape freely or liquid fuel can leak — creating a fire hazard and causing the generator to fail emissions and transport compliance requirements.
