To create a flexible connection between dosing equipment, mixers, feeders or vessels on weighing cells and supply lines, drain pipes or other forms of air transport or powder transport our silicone weighing bellows can also be fitted with a quick connect coupling.

Silicones are well known for their supple and flexible properties. These flexible connections produce little to no reactive force and therefore do not influence the weighing process. The bellows also prevent the transfer of vibrations and sound.
