Thorburn's precision engineered spherical arch rubber expansion joints are manufactured with multiple plies of tire cord fabric encapsulated with synthetic rubber and molded in a hydraulic press. Materials are fused into an inseparable homogenous mold.

Spherical Rubber Expansion Joints are constructed with a lighter wall achieving higher pressure ratings and a lower deflection force.

This superior streamline design distributes pressure evenly over a large area and the arch reduces turbulence for a smooth quite flow.

• Absorbs pipe wall and fluid noise

• Easy to install

• Reduces system stress

• Compensates for misalignment

• Prevents electrolysis and electrolytic corrosion

• Isolates vibration and motion
