The Wacker Neuson Air Seal is a genuine OEM component designed for the CRT48-25K-L, CRT48-25K-H, CRT36-23K-H, and CRT36-25K-H ride-on concrete trowels. Sourced directly from Wacker Neuson, this part carries the same specification as the seal installed at the factory, ensuring a correct, confident fit. It is compatible with both the 1220mm/48in and 915mm/36in CRT series machines, covering low-speed and high-speed configurations. When it is time to restore a worn or damaged air seal, part number is the straight swap your machine calls for.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original compression and material specifications, maintaining the correct air boundary integrity for the CRT trowel platform.
- Drop-In Fitment for CRT Series — Engineered to seat exactly as the original, with no rework or modification to surrounding components needed during installation.
- Broad CRT Series Coverage — Fits the CRT48-25K-L, CRT48-25K-H, CRT36-23K-H, and CRT36-25K-H, covering both 48in and 36in ride-on trowel variants in low-speed and high-speed configurations.
- Preserves Consistent Trowel Performance — A properly seated air seal keeps air routing controlled and stable, helping the machine deliver the consistent finish quality these trowels are built for.
- Genuine OEM Part — Supplied by Wacker Neuson as an authorized replacement, so you can order with confidence knowing the part number and specification are an exact match to the original.
An air seal on a ride-on concrete trowel controls airflow within the machine's housing or drive system, preventing pressure loss and keeping contaminants — including concrete dust and moisture — from reaching sensitive internal components. When the seal degrades or tears, it can allow air or debris ingress that accelerates wear on nearby parts and disrupts consistent machine operation. Replacing a worn air seal promptly with the correct OEM part, such as Wacker Neuson 5000088735, helps protect the surrounding components and keeps the trowel performing as intended across long finishing runs.
