Product Description

The 711 Plus expansion joint, formerly 711FRP, was developed to solve a problem unique to most non-metallic pipe: brittle components and large coefficients of expansion. The 711 Plus has integral gusset plates built into the backing ring.  The integral gusset plates eliminate the problem of cracks on the plastic flanges due to the bending forces from standard gusset plates. Just like the 711, the 711Plus also features a full-face built-in rubber face that makes it ideal for use in plastic piping applications.  The 711 can handle more movement than a Metrasphere and has a lower spring rate than the 100HT.

The 711 Plus 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

  • Ideal for reducing noise and vibration in a piping system.
  • Reduces pipe stress in your system.
  • Has full-face built-in rubber gasket
  • Handles movement in all directions.
  • Available in EPDM, Neoprene, or Nitrile elastomers with nylon cord
  • See tables for maximum temperature and pressure ratings.
