The Wacker Neuson Seal Ring is a genuine OEM component designed for the HI750 and HI900 series indirect-fired air heaters and the HP252. Sourced directly through the Wacker Neuson parts network, this seal ring carries the same specifications as the part installed at the factory, ensuring a correct fit across a broad range of HI750 and HI900 configurations — including diesel, natural gas, and dual-fuel DGM variants, as well as skid-mounted and surge-brake-equipped models. Whether you're servicing a portable unit or a skid-mounted indirect heater on a large jobsite, part number is the verified replacement to keep your equipment running at spec.
Key Features
- OEM-Grade Sealing Material — Manufactured to the same material and dimensional tolerances as the original, ensuring proper compression and leak-free performance in heating system connections.
- Drop-In Replacement — Matches the original seal ring profile exactly, seating into the same bore or fitting without rework or additional hardware.
- Broad HI-Series Fitment — Compatible with HI750 and HI900 indirect-fired air heaters across diesel, natural gas, LP, and DGM dual-fuel configurations, including skid-mounted and surge-brake variants, as well as the HP252.
- Prevents Combustion Gas and Fluid Leaks — A compromised seal ring can allow exhaust gases or heated fluid to escape the sealed circuit, reducing heater efficiency and creating unsafe operating conditions.
- Fuel and Heat System Safety — In indirect-fired heater applications, maintaining an intact seal is critical to keeping combustion and heat-exchange circuits properly isolated; this OEM part supports that integrity.
- Verified Wacker Neuson Part Number — Order with confidence using part number 5000172589, cross-referenced across the full HI750 and HI900 model range.
A seal ring forms a pressure-tight barrier between mating components in a fluid or gas circuit — in this case within the heat exchanger and burner assembly of an indirect-fired air heater. In indirect heaters, combustion gases and the heat-transfer medium must remain in separate, sealed circuits so that clean, uncontaminated heated air is delivered to the work area. When a seal ring wears, cracks, or loses its compression set, it can allow cross-contamination between circuits or permit fluid and gas leaks, both of which reduce heating output and can create hazardous conditions. Replacing a worn seal ring with the correct OEM part restores the integrity of those circuits and returns the heater to safe, efficient operation.
