The Wacker Neuson is a genuine OEM Barbed Hose Fitting designed for the HSH350, HSH380, and E1250 series hydronic surface heaters, as well as compatible pump pack configurations including the DPP33, DPP8.8, SPP4.4, and BP45 Pureheat Booster Pump. As a factory-sourced component, it meets the exact dimensional and material standards required for proper hose retention and leak-free fluid connections in hydronic heating systems. This fitting is confirmed for use across a broad range of Wacker Neuson ground heating equipment, covering LP/NG, diesel, and standard configurations. When replacing a worn or damaged barbed fitting, using the correct OEM part ensures the fluid circuit maintains the pressure integrity the system depends on.
Key Features
- OEM-Matched Barb Profile — Manufactured to the exact barb geometry specified by Wacker Neuson, ensuring hose retention strength matches the original design rather than a generic approximation.
- Secure Hose-to-Port Connection — Installs directly into the fluid circuit port; the barbed profile grips the hose interior to prevent pull-off under operating pressure and thermal cycling.
- Broad Hydronic System Compatibility — Confirmed fit across the HSH350, HSH380B, HSH380S, E1100, E1250B, E1250S, and E1250P series, plus DPP33, DPP8.8, SPP4.4, and BP45 pump packs.
- Leak-Free Fluid Circuit Integrity — A correctly seated barbed fitting prevents coolant or heat-transfer fluid loss, keeping the hydronic loop pressurized and the heating output consistent across the surface blanket or slab.
- Fuel and Fuel-Type Agnostic — Suits LP/NG, diesel, and standard heater variants within the same model families, making it a single stocking solution for mixed fleets.
A barbed hose fitting is a threaded or push-in connector with one or more raised ridges — the barbs — on the hose-side shank. In a hydronic ground heating system, these fittings form the connection points between rigid ports on pumps, heaters, and manifolds and the flexible hoses that carry heated fluid through the circuit. The barbs grip the hose interior when the hose is pressed on, creating a mechanical seal that resists both pressure spikes and the constant expansion and contraction caused by temperature changes. When a barbed fitting cracks, strips, or corrodes, the result is fluid loss from the loop — which drops system pressure, reduces heat output, and can cause the pump to run dry if left unaddressed.
