Wacker Neuson 5000168838 Bulkhead Fitting

The Wacker Neuson Bulkhead Fitting is a genuine OEM component designed for the Arctic Bear HD mobile indirect air heater. Sourced directly from Wacker Neuson, this fitting matches the original specification for a clean, correct installation with no guesswork. As an OEM part, the is manufactured to the same standards as the unit it replaces, ensuring a secure, leak-free connection in demanding heating applications. If you're servicing an Arctic Bear HD indirect air heater, this is the exact part to restore your machine to full operating condition.

Key Features

• Genuine OEM Integrity — Manufactured by Wacker Neuson to the original fluid-system specification, ensuring correct thread form, material grade, and sealing surface for a pressure-rated connection.
• Direct Panel-Mount Replacement — Designed to drop into the existing bulkhead aperture on the Arctic Bear HD, with matching thread and body dimensions for a straightforward swap.
• Confirmed Fitment — Verified for the Arctic Bear HD mobile indirect diesel air heater, so you can order with confidence that part number 5000168838 is the right fit for your machine.
• Leak-Free Fuel or Fluid Routing — A correctly seated bulkhead fitting maintains sealed, uninterrupted flow through the heater's plumbing; a worn or damaged fitting risks fluid loss and compromised heater output.
• Fuel System Safety — On a diesel indirect air heater, a properly rated bulkhead fitting is critical to containing fuel or combustion-related fluids safely — never substitute with an unrated or mismatched fitting.

A bulkhead fitting is a through-panel connector that allows a fuel, fluid, or air line to pass cleanly and securely through a wall or panel in the heater assembly. It creates a sealed, anchored passage that prevents fluid migration, vibration-related loosening, and panel wear at the line entry point. When a bulkhead fitting cracks, strips, or loses its seal, the result can be fluid leakage at the panel, reduced system pressure, and potential safety hazards on a diesel-fueled machine — making prompt replacement with the correct OEM part essential.
