AVK support bushes are designed for PE pipe installations to ensure correct internal support when using tensile couplings or flange adaptors, such as:

AVK Combi-flange
Supa Plus™ or Supa Maxi™ couplings

They also help restore pipe roundness and maintain correct chamfering—especially useful for coiled PE pipes.
