The Wacker Neuson is a genuine OEM 5/16 Barb X 1/4 NPT Fitting designed for the LTW20Z-1 and LTW20Z-3 series light towers. Sourced directly from Wacker Neuson, this fitting meets the exact specifications required for the fuel or fluid line connections on these machines. It covers a wide range of LTW20Z configurations, including standard Tier 4i, Cold Weather, Custom, and Vertical Stack variants. Confirm your model and machine number before ordering to ensure an accurate match.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's exact thread and barb specifications, ensuring correct sealing geometry for both the 5/16 barbed hose connection and the 1/4 NPT threaded port.
- Direct-Connect Installation — The 5/16 barb end seats securely onto compatible hose lines, while the 1/4 NPT male thread engages directly into the receiving port with no modification to the line or fitting needed.
- Broad LTW20Z Series Coverage — Verified fitment across LTW20Z-1 and LTW20Z-3 light tower variants, including LED, Metal Halide, Cold Weather, Skidded, and Vertical Stack configurations on Isuzu Tier 4i power units.
- Leak-Free Fluid Routing — A correctly seated barb fitting maintains consistent fluid pressure and flow through the connected line; a cracked or loose fitting can introduce air into the system or allow fluid loss, disrupting machine operation.
- Verified Part Number Traceability — Part number 5000179318 is the Wacker Neuson OEM reference, giving you a direct cross-check against your parts manual or service diagram before purchase.
A barb-to-NPT fitting serves as the transition point between a flexible hose line and a threaded port on the machine's fluid system. The barbed end grips the interior of the hose to hold it in place under pressure, while the tapered NPT thread creates a tight mechanical seal in the receiving port. On light towers such as the LTW20Z series, these fittings are commonly used in fuel or coolant routing circuits. When a fitting cracks, strips, or corrodes, it can cause fluid leaks, pressure loss in the line, or hose separation — any of which can interrupt extended-run lighting operations on the worksite.
