The Wacker Neuson Air Horn Gasket is a genuine OEM component designed for the RD12-90 Tandem Roller and CRT36-25 Ride-on Trowel series. Sourced directly from Wacker Neuson, this part carries the same specifications as the original, ensuring a proper seal at the air horn junction without the guesswork of an off-brand substitute. It fits both the standard and foldable ROPS configurations of the RD12-90, as well as CRT36-25 models equipped with the Wheel Kit, covering the most common variants in the field.
Key Features
- OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and compression specifications, so the air horn seals cleanly and consistently every time.
- Direct-Fit Replacement — Matches the original gasket profile exactly, dropping straight into place at the air horn interface with no trimming or adjustment needed.
- Broad Model Coverage — Confirmed fitment across RD12-90 Tandem Rollers (standard and foldable ROPS variants) and CRT36-25 Ride-on Trowels, including the Wheel Kit-equipped model.
- Fuel System Integrity — A correctly seated air horn gasket maintains the proper air-fuel pathway; a deteriorated or missing gasket can allow unmetered air into the system, disrupting carburetion and causing erratic engine behavior.
- Fuel Safety Compliance — As a fuel system sealing component, using a genuine OEM gasket ensures the air horn connection meets the original design intent, reducing the risk of air leaks that can affect safe, consistent engine operation.
The air horn gasket forms an airtight seal between the air horn and the carburetor body, ensuring that the air entering the fuel system is properly metered through the designed passages. Without a properly functioning gasket, uncontrolled air can enter the fuel circuit, leaning out the mixture and causing hard starting, rough running, or stalling under load. Over time, heat cycling and vibration cause gasket material to compress and crack, making this a routine but critical service item on compaction and finishing equipment.
