Calibration Hoses

Calibration Hoses are used in open-end installations (blind-shot) and pull-in-place applications to press the liner against the host pipe during the curing process.
Calibration hoses are also used to manufacture glued open-end liners and prevent excessive swelling of the liner in free space.
Flexible calibration hoses made of silicone are used in patch repairs and UV-curing.
