Fl anged Single Sphere Rubber Expansion Joints  ★★★
  • J13
  • Series J13 flanged single sphere rubber expansion joint is designed to compensate various movements in pipeline, such as the movements by heat-generated expansions, settlements of terrain or building structures, rolling movements and assembly errors, machinery vibrations, water hammers, etc.

    FEATURES

    • All rubber compounds for lining are specifically formulated to provide maximum sound and heat insulation as well as abrasion resistance
    • A strong, bias-ply construction, high-strength nylon fabric inside rubber Round steel rings embedded in the liner give maximum strength to the expansion joint while under pressure or vacuum service
    • Flanges are full-faced and make an integral part of the joint to insure a tight reliable seal, no gasket are necessary
