The Wacker Neuson Radiator Cap is a genuine OEM component designed for CUB700GM series mobile indirect fired air heater units, including the double axle trailer configuration and the diesel unit with genset. As a direct OEM replacement sourced through authorized Wacker Neuson parts channels, the meets the original design specification for pressure rating and sealing performance on these mobile climate units. It installs directly in place of the original cap with no adaptation needed, making it the straightforward choice for scheduled maintenance or emergency field replacement. Keep a spare on hand for any CUB700GM unit in your fleet to avoid unplanned service interruptions during heating season.
Key Features
- Correct Pressure Rating for Hydronic Systems — Engineered to the exact relief pressure spec of the CUB700GM cooling circuit, ensuring the system builds and holds the right operating pressure without over- or under-pressurizing.
- Positive Sealing Surface — The cap's sealing gasket mates directly to the original filler neck geometry, delivering a leak-free connection on every installation.
- Genuine OEM Quality — Sourced directly from Wacker Neuson, this part carries the same material and dimensional standards as the cap installed at the factory on CUB700GM heater trailers.
- Broad CUB700GM Coverage — Confirmed fitment across the double axle Mobile Air Heater Trailer and the Diesel with Genset indirect fired heater variants in the CUB700GM family.
- Fuel and Coolant Safety Compliance — A properly rated radiator cap is critical to controlling coolant system pressure; a failed or incorrect cap can cause coolant loss, overheating, and potential scalding hazard during service.
A radiator cap does more than seal the coolant reservoir — it acts as a pressure regulator for the entire cooling circuit. By holding coolant under a calibrated pressure, the cap raises the boiling point of the coolant and keeps the system operating efficiently across a wide range of ambient temperatures. When the cap wears out or loses its ability to hold pressure, coolant can boil over, the engine or burner assembly can overheat, and the machine may shut down mid-operation. On mobile heater units like the CUB700GM, where reliable heat output is critical on cold-weather job sites, a correctly functioning radiator cap is a small but essential part of uninterrupted performance.
