Product Description

The MetraPak’s unique design is capable of absorbing large amounts of axial movement (up to 12” for single joints and 24” for dual joints) in pipelines and process systems, reducing the number of joints and anchors. Ideal for high pressure or high temperature applications.  This time-tested design allows for repacking while the joint is in service.

Product Highlights

  • All in-line expansion joints develop anchor loads and require guiding.  Refer to the design guide or consult Metraflex or your local representative for more information.
  • Proudly made in the USA.
  • Can be customized with anchor bases and branch service.
