Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional standards, ensuring the cap seats and seals exactly as designed for concrete pump air stack assemblies.
- Direct-Fit Replacement — Engineered to drop into the C30HD and VH4D air stack assembly without modification, matching the original mounting interface and profile.
- Confirmed Fitment — Specifically validated for C30HD and VH4D concrete pump models, eliminating guesswork when sourcing this component.
- Protects Air Stack Integrity — Keeps the air stack sealed against debris and moisture ingress, which is critical to maintaining consistent pump operation and preventing contamination inside the assembly.
- Long-Term Durability — Built from materials selected for the demanding environment of concrete pump equipment, standing up to the dust, vibration, and exposure common on active pour sites.
The air stack cap sits at the top of the air stack assembly on the concrete pump, closing off the stack to prevent debris, water, and foreign material from entering the system. A properly sealed air stack helps maintain correct airflow and pressure conditions within the pump, supporting consistent performance during concrete placement operations. When the cap is damaged, missing, or worn, contamination can enter the assembly and lead to accelerated wear or interference with pump function.
