What Is a Flexible Connector or Expansion Joint?
Flexible connectors are devices installed in piping systems to absorb movement, reduce vibration, and compensate for misalignment or thermal expansion. They protect pumps, valves, and building structures from stress caused by system motion—whether due to flow dynamics, heat changes, or equipment startup/shutdown.

FAQ: EFP Connectors & Expansion Joints
What’s the difference between rubber and metal connectors?
- Rubber joints excel at absorbing noise and vibration, while metal braided connectors offer superior pressure and temperature tolerance. Your application dictates the best fit.
Do I need control rods with my rubber expansion joints?
- Yes—especially in systems without anchors or where thrust forces may occur. Control rods limit movement and prevent overextension.
Can EFP connectors be installed vertically or horizontally?
- Yes. EFP designs allow for flexibility in installation orientation—just ensure proper support and alignment for the system layout.
How long do EFP flexible connectors last?
- With proper sizing and installation, they can last 10+ years in HVAC or hydronic systems. Harsh environments may shorten lifespan.
Are custom-length or end connection options available?
- Absolutely. EFP can manufacture to specific lengths and provide threaded, flanged, grooved, or weld ends to match your system.
