Rigid Coupling

YINUO, a prominent manufacturer and supplier of Rigid Couplings in China, consistently offers a selection of top-tier Rigid Couplings at competitive factory prices. Meticulously crafted for resilience and reliability, our products guarantee peak performance and utmost satisfaction for our discerning clientele.

Rigid coupling fittings are mechanical devices used to join ductile iron or steel piping components together in a rigid, bolted connection.

  • They are used with piping elements that have modular grooved ends, such as grooved pipe, elbows, tees, etc. Made of steel or ductile iron.
  • Have two halves that bolt together around the grooved ends of the pipes being joined. The inner edges have machined serrations that mate with the pipe grooves.
  • When bolted, the serrations cut into the pipe grooves to form a rigid, mechanical bond that joins the pipes like a flangeless welded joint.
  • Manufactured in various sizes to join piping schedules 5 to 40.
