All threaded joints have the same limitations no matter if they are made of PPSU or metal: Hemp cannot be used to seal the joint. The height of the male thread cannot be greater than the heigth of the female thread. Conical threads cannot be used together with straight threads. Male threads must have the same thread pitch as female threads.
