Open Flex Wrap-Around Pipe Couplings

Straub pipe couplings are designed for joining two pipes or tubes together in piping systems of vacuum, pressure or suction lines. These units feature a unique low-profile design which wraps around the pipe orifice to create a leak-free seal and an EPDM split gasket to withstand temperatures ranging from -4 to 212 deg F at a maximum pressure of 232 psi. They are also capable of compensating for axial & angular deflections, dampening noise & vibrations and handling pipe misalignments. Choose from a wide range of these open flex wrap-around pipe couplings in 1-1/2, 2, 2--1/2, 3, 4, 5 and 6 inch pipe sizes on Raptor Supplies.

Working Mechanism

  • Straub open flex couplings act as an expansion joint.
  • In order to use these couplings, the pipes must be properly anchored and restrained.
  • They require no special tools or pipe-end preparation.
  • These pipe couplings only need a torque wrench for a secure and safe pipe connection that seldom needs re-tightening.

Features

  • Straub open flex couplings feature a low-profile design that wraps around the pipe orifice to create a leak-free seal.
  • These units have an EPDM split gasket to withstand temperatures ranging from -4 to 212 deg F, at a maximum pressure of 232 psi.
  • The patented grip ring offers superior holding power on hard-surfaced pipes.
  • These couplings compensate for axial & angular deflections, dampening noise & vibrations and handling pipe misalignments.
