Rubber Expansion Joint Ultra-Superflex TU Series | Union Bellow | Union Rubber Bellow | Rubber Union Flexible Joint

RUGAVAL Ultra-Superflex union joints (USTU) are precision folded in hydraulic presses. The spherical design ensures that internal pressures are exerted in all directions, distributing the forces evenly over a large area. The spherical design acts as a free-flowing arch, reducing turbulence and growth due to pressure thrust forces. Ultra-Superflex connectors are constructed with high-quality EPDM tube and cover and nylon tire cord reinforcing. USTU Series EPDM connectors offer high-temperature EPDM rubber for tube and cover construction. Galvanised malleable iron threaded female union ends are standard. Special cable restraint attachments surround each end to prevent the connector from over-extending due to pressure thrust. A steel body ring encircles the rubber between the spheres to provide stability under pressure.
