RUBBER EXPANSION JOINTS AND PUMP CONNECTORS

250°F MightySphere pump connector/expansion joint with Kevlar®

The MightySphere pump connector and expansion joint protects your pumps and reduces noise and vibration.

A durable joint for piping systems reaching temperatures up to 250°F (121°C), the Metraflex MightySphere™ joint differs from standard EPDM expansion joints by integrating Kevlar® cording and peroxide-cured EPDM. It is perfect for high-temp applications requiring modest pipe movement/expansion at higher temperatures.

The rugged, long-lasting material and construction will provide years of trouble-free operation at high temperature.

An anchor wire, fully-wrapped with Kevlar® corded material, ensures a positive seal between the body and the floating flange.

  • Kevlar® reinforced, peroxide-cured EPDM rubber greatly enhances tolerance to high temperatures
  • Anchor wire wrapped with Kevlar® corded material ensures a positive seal between the body and the floating flange
  • Reduces noise and vibration
  • Isolates and protects the pump
  • Available in single and doublesphere styles.
