Uniform pressure makes or breaks a liner, and that’s exactly what a calibration hose delivers. Choose clear stitched PVC when you want eyes on the resin bleed-out, switch to white TPU for tougher pulls through offsets, or step up to full silicone when steam or high-temp UV is on the schedule. Choose violet calibration hose to make perfect open-end installation

Diameters start at DN 50 and climb into mid-mains, with variable lengths available.
