The Shear Banded Bush range is used with DEKS shear banded couplings when joining pipelines of dissimilar materials or when the pipe’s outside diameter is smaller than the nominal size of the coupling. The bushes are available in thickness options of 5 mm, 8 mm, and 16 mm, and are suitable for multiple pipes outside diameter groups used in sewer, stormwater, and wastewater systems, covering an OD range from 105 mm through to 265 mm.
The bush provides the additional thickness required to join dissimilar pipe materials and match the standard sizing of the shear banded coupling. The bush assists in distributing clamping forces from the stainless steel bands evenly onto the pipe surface, reducing the risk of misalignment. The more uniform contact interface helps maintain sealing performance, minimise vibration and limit movement caused by soil loads or surface loading in underground applications.
Shear banded couplings and the corresponding bushes are WSAA approved for use in Australia and are suitable for connecting dissimilar pipe materials in sewer, stormwater, wastewater, and related civil infrastructure systems.
