Renfert Connection Sleeve for Sandblaster Silo
This Renfert connection sleeve for sandblaster silos connects the flexible hose directly to the sand container. Due to constant abrasive flow, this part is designed as a wear component and should be replaced regularly to maintain consistent blasting performance.
Why replace the connection sleeve?
- Continuous abrasive flow causes progressive internal diameter wear.
- An incorrect diameter leads to reduced blasting precision.
- Typical symptoms: pulsing / sputtering, irregular flow, abrasive released in bursts.
- Replacement restores a stable, controlled abrasive flow.
Applications
This Renfert silo connection sleeve is intended for Renfert Vario sandblasters (older models). It ensures a secure interface between the flexible hose and the sand container.
Before ordering, we recommend checking your silo connection type, as some older versions may use a different fitting.
Instructions & lab tips
- Disconnect the flexible hose from the worn sleeve.
- Clean the thread thoroughly on the silo before reassembly.
- Screw in the new sleeve without overtightening to protect the thread.
- Secure the hose using the included hose clamp.
Proper installation ensures optimal sealing, smooth abrasive delivery, and consistent blasting quality.
