ATRA-FLEX® Flexible Couplings are proudly manufactured in the USA


  • Standard hubs and rings are machined from Solid Carbon Steel rounds and tubing, maintaining tight tolerance’s which maintains excellent coupling balance.
  • Stainless steel in grades 303,304 and 316 are also available for corrosive environments and the food industry.
  • We offer a cost savings alternative to Stainless steel with a Melonite® Process.

Melonite® process gives our solid carbon steel a uniform case hardening up to an average of 57.6 RC, which significantly prevents wear and corrosion.
