RUBBER EXPANSION JOINTS

Hand-crafted rubber expansion joints available in single- and multiple-arch designs are custom-built to fit your application requirements. Options include PTFE-lined, concentric reducing, eccentric reducing, filled arch, lightweight, and off-set configurations. With a wide range of elastomers, our Unaflex expansion joints can be designed to operate up to 200 psi and with temperatures up to 500 F in sizes from ½” up to 144”.


As specifically engineered products that are inserted in a rigid piping system, Our Rubber Expansion Joints will:


 Absorb movement

 Improve thermal stability

 Relieve system strain due to thermal change, load stress, pumping surges, wear of settling

 Reduce mechanical noise

 Compensate for misalignment

 Eliminate electrolysis between dissimilar metals

METAL BELLOWS EXPANSION JOINTS

Custom-engineered single- and dual-bellows designs made from 18-8 stainless steel alloy 321 with high intergranular corrosion resistance. Options include PTFE-lined, universally-tied, pressure-balanced, Gimbal, and hinged, among other configurations. With a wide range of metals, our Unaflex metal bellows expansion joints can be designed to operate up to 300 psi and with temperatures up to 1500 F in sizes from 2” up to 144”.
