Wacker Neuson 5200006847 Adapter Fitting #6 JIC M to 3/8 NPTM 90

The Wacker Neuson is a genuine OEM Adapter Fitting #6 JIC M to 3/8 NPTM 90 designed for the G100 and G120 Custom T4i portable generators. As a factory-sourced component, part delivers the exact thread form, seating geometry, and 90-degree orientation specified by Wacker Neuson for these machines. It drops directly into the original hydraulic or fuel line routing without reworking surrounding hardware. Whether you are replacing a damaged fitting or completing a fluid-system service, this genuine OEM part keeps your generator running to the spec it left the factory with.

Key Features

• OEM Thread Accuracy — Manufactured to Wacker Neuson specification with correctly sized #6 JIC male and 3/8 NPTM threads, ensuring a leak-free metal-to-metal seat on the JIC side and a proper tapered-thread seal on the NPT side.
• 90-Degree Routing by Design — The right-angle body matches the original line routing inside the G100 and G120 generator enclosures, allowing hoses and hard lines to connect without bending or stressing adjacent fittings.
• Direct OEM Replacement — Sourced directly from Wacker Neuson, part number 5200006847 replaces the original fitting on a one-for-one basis with no thread chasing or adapter stacking required.
• Confirmed Fitment for G100 and G120 Custom T4i Generators — Verified for use on the G100 Custom T4i and G120 Custom T4i generator models, so you can order with confidence that this is the correct part for your machine.
• Fluid-System Integrity — A correctly seated adapter fitting maintains proper flow and pressure in the connected circuit; a cracked, cross-threaded, or worn fitting can cause fluid loss, pressure drop, or contamination that affects generator operation.
• Fuel and Fluid System Safety — Correct thread engagement and sealing at every fitting junction is critical in fuel and fluid circuits; using the OEM-specified fitting eliminates the risk of mismatched thread forms that can lead to leaks under operating pressure.

An adapter fitting serves as the transition point between two different thread standards within a fluid circuit — in this case, converting a #6 JIC male connection to a 3/8-inch NPT male port at a 90-degree angle. The JIC side forms a leak-tight metal-to-metal flare seat, while the NPT side relies on a tapered thread engagement to seal against fluid pressure. When a fitting cracks, corrodes, or develops a compromised seat, the resulting leak can introduce air into the circuit, cause fluid loss, or allow contamination — any of which can disrupt the generator's operation and create a potential hazard in the work environment.
