The Wacker Neuson Gasket is a genuine OEM component designed for the HSH700 and HSH650 hydronic surface heaters. Sourced directly from Wacker Neuson, this gasket delivers an exact fit to the original specification, ensuring a proper, leak-free seal within the heating system. It is the correct replacement for both the HSH700 and HSH650 series, giving operators confidence that the repair is done right the first time.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to the original material and compression specification, ensuring the gasket seats and seals correctly within the HSH system rather than allowing fluid or pressure bypass.
- Direct Drop-In Replacement — Matches the original mounting interface on HSH700 and HSH650 heaters, installing in the same position and orientation as the factory part.
- Confirmed HSH Series Fitment — Verified for the HSH700 and HSH650 hydronic surface heater models, so you can order with confidence.
- Maintains System Pressure and Flow — A properly seated gasket keeps the hydronic circuit fully pressurized; a failed or degraded gasket can cause fluid weeping, loss of heating efficiency, and potential surface damage to curing concrete.
- Fuel and Fluid System Safety — In a hydronic heater, a compromised gasket can allow heated fluid to escape near combustion or electrical components, making correct gasket condition a genuine safety consideration during service.
A gasket creates a static seal between two mating surfaces in the heater's hydronic circuit, preventing heated glycol solution from leaking at joints, connections, or heat exchanger interfaces. In a hydronic surface heater like the HSH700 or HSH650, maintaining a tight seal throughout the fluid circuit is critical — even a minor leak reduces system pressure, lowers heating output, and can cause uneven curing of concrete slabs. When a gasket hardens, cracks, or is compressed beyond its service life, it loses the ability to hold a seal, making timely replacement essential to keeping the heating circuit operating at full capacity.
