Product Description

The Mightysphere™ rubber expansion joint is 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.
