The Slurryflex SJD-Series Rubber Vibration Joint is designed to dampen vibration and reduce noise in slurry pipework. Having no arch, it has limited movement capability compared to expansion joints but similarly relieves stress and compensates for pipe misalignment.

Standard applications for the Slurryflex vibration joint are the transfer of abrasive slurries, sand, and gravel in mineral processing plants and tailings pipelines. It can also be customised for chemicals, acids, and hydrocarbons.

All of our Slurryflex expansion joints are custom made in Australia from premium materials. Tell us about your application and we’ll help you choose the right materials, size, length, and end connections.
