The Wacker Neuson Nipple Fitting is a genuine OEM component designed for the E2200, E3000, E3000 ES, S3000, E700M, HSH650, and HSH700G series hydronic surface heaters and ground heaters. As a direct OEM replacement, part is manufactured to the exact specifications required to maintain a leak-free, pressure-rated fluid connection within the heating system. This fitting is confirmed compatible across a wide range of E-series and HSH-series configurations, including lift bail, generator, and TC variants. Keep a spare on hand to avoid extended downtime during cold-weather operations when these machines are working hardest.
Key Features
- Genuine OEM Leak Integrity — Manufactured to exact thread form and material spec, ensuring a pressure-tight seal in the hydronic fluid circuit without improvised workarounds.
- Drop-In Thread Match — Replicates the original port dimensions exactly, so the fitting installs directly into the existing manifold or hose connection without rework.
- Broad HSH and E-Series Compatibility — Fits E2200, E3000, E3000 ES, S3000, E700M, HSH650, and HSH700G models across ground heater, hydronic surface heater, and lift bail configurations.
- Protects Heating System Efficiency — A sound nipple fitting maintains correct fluid flow and circuit pressure; a cracked or stripped fitting causes fluid loss, pressure drop, and reduced heat output to hoses and blankets.
- Verified Wacker Neuson Part Number — Sourced directly under OEM part number 5000168702, so you can order with confidence that you are receiving the correct component for your specific machine.
A nipple fitting is a short threaded connector used to join two sections of hose, pipe, or ported components within the hydronic fluid circuit of a surface heater or ground heater. In machines like the E3000 and E2200 series, the hydronic circuit carries heated fluid from the boiler unit through insulated hoses and heating blankets to thaw frozen ground or cure concrete in cold conditions — and every connection point in that circuit must hold pressure reliably. When a nipple fitting becomes cracked, corroded, or stripped, it allows fluid to escape, dropping system pressure and reducing heat delivery to the work surface. Replacing a failed fitting promptly with the correct OEM part restores full circuit integrity and keeps the heating system performing at rated capacity.
