Product Features

It is composed of two bellows connected by the intermediate pipe and tie rod, end plate and spherical and conical gasket. It mainly absorbs the transverse displacement, and can also be used to compensate the axial, transverse, angular and arbitrary displacement combined by these three forms.It is recommended to install the double pull rod type expansion joint in the middle short pipe arm of the 90° z-shaped pipe to compensate for the axial displacement of the long pipe at both ends.
