Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and thread specifications, ensuring correct sealing performance in fuel or fluid line connections on HI and HDR heater systems.
- Drop-In Thread Compatibility: — Matches the original port sizing and thread pitch exactly, threading directly into the heater assembly without reworking fittings or connections.
- Broad HI and HDR Series Coverage: — Fits an extensive range of Wacker Neuson indirect air heaters and direct fired radiant heaters, including HI 90, HI 110HD D, HI 120HD, HI 200D, HI 300HD D, HI 400HD D, HDR 115, HDR 155, and more.
- Leak-Free Fluid Transfer: — A properly seated nipple maintains a secure, pressure-tight connection in the heater's fuel or coolant circuit; a damaged or corroded nipple can result in fluid leaks, loss of heat output, and heater shutdown.
- Fuel System Safety: — As a component in the heater's fuel delivery path, using a correctly rated OEM nipple is essential to maintaining a safe, leak-free connection on diesel-fired heating equipment.
A nipple is a short threaded fitting used to connect two sections of pipe, hose, or ported components within a fluid circuit. On Wacker Neuson HI and HDR series heaters, this fitting plays a role in routing fuel or fluid flow between key heater components, maintaining a sealed, pressure-consistent pathway. When a nipple becomes corroded, cracked, or stripped, it can allow fluid to escape the circuit, which on a diesel-fired heater may lead to fuel leaks, degraded combustion, reduced heat output, or an automatic safety shutdown. Replacing a worn nipple promptly with the correct OEM part restores circuit integrity and keeps the heater operating as intended.
