The EK-HD PETG Inserts are EK's way of battling against potential hazards that the use of PETG tubes present.
PETG tubes are extremely popular because of the ease of use and their flexibility. On the other hand, PETG tubing is prone to deformation when exposed to high temperatures (40C and above). The deformation rate depends on the duration and maximum temperature reached. These temperatures can be reached with pump failures, water block clogging, etc.
The EK-HD PETG Inserts provide a safety measure for 16mm OD / 12mm ID PETG tubes which prevents the tube wall from collapsing inside the compression fitting.
The EK-HD PETG Insert is low profile and it is not visible when in use with any of the EK hard tubing fittings.
