Wacker Neuson 5200023442 Bushing 3/8 NPT

The Wacker Neuson Bushing 3/8 NPT is a genuine OEM component designed for the HIF 690 Flameless Heater. As a factory-sourced part, it carries the same specifications as the original and threads directly into the port it was built to serve — no guesswork on thread sizing or seat compatibility. Wacker Neuson genuine OEM parts are manufactured to the same standards as the components installed at the factory, making the a straightforward, confidence-inspiring choice when servicing the HIF 690.

Key Features

• Correct Thread Form, Every Time — Cut to 3/8 NPT specification so the tapered thread engages cleanly and seals without over-torquing or thread chasing.
• Genuine OEM Sourcing — Manufactured by Wacker Neuson to the same material and dimensional tolerances as the bushing originally installed on the machine — not a generic pipe fitting.
• Direct Port Replacement — Threads directly into the existing 3/8 NPT port on the HIF 690 Flameless Heater with no adapters or modifications to surrounding fittings.
• Verified HIF 690 Compatibility — Confirmed fitment for the HIF 690 Flameless Heater (model 5200012622), eliminating the risk of ordering an incompatible pipe size.
• Fuel System Integrity — A properly seated bushing maintains a leak-free connection in the heater's fuel or fluid circuit; a damaged or cross-threaded bushing can allow seepage that compromises combustion safety and output consistency.

A bushing is a threaded pipe fitting used to connect or close off ports of different sizes within a fluid or fuel circuit. In a flameless heater like the HIF 690, the bushing provides a sealed transition point that keeps the fuel delivery or ancillary fluid circuit pressure-tight and correctly routed. When a bushing corrodes, cracks, or develops damaged threads, it can allow fluid seepage that disrupts heater performance, creates a potential fire hazard, or causes the unit to shut down on a fault condition — making timely replacement essential for safe, consistent heat output on the jobsite.
