Product Description

The Mightysphere™ is the joint in the Metrasphere™ family that can handle higher temperature and pressures.  These higher ratings are a result of enhancements we have made to the materials in the Mightysphere. The Metraflex MightySphere™ joint differs from standard EPDM expansion joints by integrating Kevlar® cording instead of nylon reinforcements, peroxide-cured EPDM cover and tube, and the seat is anchored with a solid steel ring.

The Mightysphere is most commonly used as a pump or equipment connector.  It can also be used as an expansion joint if EJMA guidelines are followed.  Control rods are optional but recommended.

Product Highlights

  • The Mightysphere still includes all the value of the Metrasphere:
  • Reduces pipe stress in your system.
  • Features Split Steel Floating flanges to make up for companion flanges that are not properly two holed.
  • Handles movement in all directions.
  • Self-cleaning.
  • Does not require a gasket.
  • See tables for maximum temperature and pressure ratings.
