Key Features

- Direct-Fit for ST45 — Designed specifically for the ST45 concrete pump; installs in place of the original without modification to mounting points or control linkage.
- Restores Full Control Response — A worn or damaged knob cartridge can result in imprecise or unresponsive control input; replacing it with this part restores clean, positive actuation.
- Confirmed ST45 Compatibility — Fitment is verified for ST45 series swing tube concrete pumps, so you can order with confidence that this is the correct part for your machine.
- Durable Under Jobsite Conditions — Built to withstand the repetitive use and demanding environment typical of concrete pump operation, maintaining consistent control function over extended service life.
The knob cartridge is the internal mechanism within a control knob assembly that translates the operator's hand input into a precise, repeatable action — whether adjusting flow, direction, or another operational parameter on the ST45. When the cartridge wears out or fails, the control knob may feel loose, slip, or fail to hold its set position, which can affect the accuracy and safety of pump operation. Replacing the cartridge with a genuine OEM part like this part restores the tactile feedback and locking precision the operator depends on during a pour.
