Sold in 100-meter (328′) rolls

Transitional 4.5 mm liner, can be used for non-transitional installs. It can be shot with or without a calibration tube.

Repiper FlexMax creates a beautiful saturated finish and is easy to install. However, stretch control is more difficult than with the Repiper S liner. But by using the Repiper Preliner, you can avoid overstretching into tie-ins in the non-transitional part of an install. Especially if you have a reinstatement robot, it can be tricky to reinstate if the liner is stretched too much into the tie-in.
