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.
