Product Description

SDSX Grooved Rigid Coupling

Systems & Performance

SDSX Grooved mechanical couplings(GMC) are available in both rigid and flexible models.

A rigid coupling is used in applications where a rigid joint is desired,similar to that of a traditional flanged,welded ,or threaded connection.

To be considered rigid,a coupling would allow less than one degree of deflection or angular movement

 

Description

SDSX rigid coupling is designed from 1"-12", and pressure is 300psi/2070 kPa.

Bolts/Nuts: Heat-treated plated carbon steel, meeting its mechanical properties Grade 8.8.

Gaskets: EPDM, silicon rubber and Nitrile rubber.
