The Wacker Neuson is a genuine OEM Hydraulic Elbow.25NPT 90 Degree Street Brass designed for the HIF 690 Flameless Air Heater. Sourced directly from Wacker Neuson, this fitting matches the exact thread specification, angle, and material grade called out in the original equipment design. Verify your model number against the HIF 690 series before ordering to confirm fitment for your specific machine configuration.
Key Features
- Brass Construction for Hydraulic Service — Solid brass body resists corrosion and provides the thread integrity required for reliable hydraulic line connections in a heater environment.
- Correct .25NPT Thread Specification — Machined to .25NPT standard, ensuring a leak-free seal when mated to compatible hydraulic ports without thread chasing or re-tapping.
- 90-Degree Street Configuration — The street-elbow design allows one end to thread directly into a fitting or port, keeping the hydraulic line routed at the precise angle engineered for the HIF 690 layout.
- Genuine OEM Part — Produced to Wacker Neuson's original specifications, so thread pitch, wall thickness, and dimensional tolerances match the factory fitting exactly.
- HIF 690 Flameless Air Heater Fitment — Confirmed for the HIF 690 Flameless Air Heater; cross-reference part number 5000170458 against your machine's parts diagram before ordering.
A street elbow fitting like the Wacker Neuson 5000170458 connects and redirects hydraulic fluid lines within the heater's hydraulic circuit, allowing the plumbing to change direction in a confined space without requiring a separate union. On flameless air heaters such as the HIF 690, the hydraulic system drives key internal components, so a fitting that leaks or fails under pressure can starve those components of flow and cause the unit to shut down or underperform. Replacing a damaged or weeping elbow with the correct OEM fitting restores a sealed, pressure-rated connection and keeps the hydraulic circuit operating as designed.
