The traditional problem with PTFE has always been that sizes over ¼” become less flexible and easy kinked & broken during movement.   The typical solution is to use conventionally convoluted PTFE liners, but the inner convolutions make the hose difficult to assemble (harder to seal) and reduces flow rates due to more turbulent flow, which means energy loss and higher temperatures in plate freezers.

The Freezertech hose features a unique internally smooth PTFE liner, with external convolutions to retain flexibility in larger sizes such as the ½” and ¾” typically used in plate freezer systems.
