EZ-FLO® Style 206

Expansion joints for general service applications

Style 206 EZ-FLO® expansion joints contain a single wide flowing arch, eliminating the need for filled arches on slurry services. Suitable for high pressure applications, their self-flushing design eliminates media buildup and reduces fluid turbulence.

Style 206 EZ-FLO® can be designed to meet the requirements of ASTM F1123 and Navy/Coast Guard Specification 46CFR56.60-25(E).

Standard Design

  • Tube — Standard chlorobutyl liner extends to outer edge of the flange for excellent chemical resistance. The flowing arch design adds pressure resistance and reduces product buildup. Seamless tube creates a positive flange seal without gaskets.
  • Body — Rubber impregnated tire cord and polyester cross-wrapped in bias-ply construction.
  • Cover — Homogeneous layer of chlorobutyl elastomer extends to the outside edge of the flange. Coated with a weather-resistant protectant.

Optional Configurations

  • Custom drilling: ANSI, DIN, AWWA, BS, JIS, and special drilling patterns available on request
  • Extended Face-to-Face (pressure/vacuum ratings may be affected)
  • Accomodate misalignment: lateral, angular, and torsional offsets
