The Slurryflex SJA-Series Single Arch Rubber Expansion Joint provides vibration control, compensates for pipework misalignment, and allows for thermal expansion in abrasive slurry applications. The single-arch configuration increases the range of movement of the joint.

This expansion joint is suited to the transfer of abrasive slurries, sand, and gravel in mineral processing plants, and tailings lines. It’s also available in custom designs for specialty applications such as fluids or slurries containing 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.
