Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's exact material and dimensional spec, ensuring the plug seals ports completely without leakage or blow-off under operating pressure.
- Direct Drop-In Fitment — Engineered to the original port size and profile, so it seats fully and locks in place without modification or additional hardware.
- Confirmed Heater Series Compatibility — Verified fit for the HDR 155, HDR 115, and HDR 45 direct fired radiant heater models.
- Protects Open Ports During Service — Keeps fuel, air, or fluid passages capped and free of debris during maintenance or storage, helping preserve system cleanliness and component integrity.
- Fuel System Safety — A correctly seated cap plug prevents unintended fuel or vapor release at open ports, an important consideration when servicing any combustion-based heating equipment.
A cap plug is used to seal open ports, fittings, or passages on a machine during servicing, storage, or when a connected line or component is temporarily removed. On direct fired radiant heaters like the HDR series, maintaining sealed passages is critical to preventing contamination of fuel circuits and protecting internal components from moisture and debris. A missing or damaged cap plug can leave sensitive ports exposed, risking blockages, fuel system contamination, or unsafe vapor exposure during maintenance.
