Product Description

The Doublesphere is another part of the Metrasphere family of joints, our most popular rubber joints.  The Doublesphere handles more movement than a Metrasphere and provides all the value.

The Doublesphere 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 always recommended.

Product Highlights

  • Ideal for reducing noise and vibration in a piping system.
  • Reduces pipe stress in your system.
  • Features Floating flanges to make up for companion flanges that are not properly two holed.
  • Handles movement in all directions.
  • Available in EPDM, Neoprene, or Nitrile elastomers with nylon cord reinforcement.
  • Self-cleaning.
  • Does not require a gasket.
  • See tables for maximum temperature and pressure ratings.
