Heavy Duty Expansion Joints

A PosiFlex elastomeric expansion joint is a flexible connector fabricated of natural or synthetic elastomer, fabrics and, where necessary, metallic reinforcements. They provide stress relief in piping systems caused by thermal and mechanical vibration and/or movement. It can also be used to overcome problems of noise. Rubber, as a material of construction in the PosiFlex expansion joint, has superior noise and vibration eliminating qualities over all other types of material. 

The standard PosiFlex expansion joint is of the spool-type with a single arch and flanged ends. The movement capability of the PosiFlex expansion joint is dependent upon the arch. If greater expansion or contraction is required than can be absorbed by a single arch, then a multiple arch joint can be used with up to four arches.
