AJ550R

It is a differentiated product from the existing Grooved joint method, and it is a Grooved joint in which pipes and fittings can be easily fastened without breaking down bolts/nuts and rubber rings.

  • One-stop Grooved joint Rigid type
  • Joint material: Spherical graphite cast iron (GCD450)
  • Gasket material: EPDM
  • Bolt/nut material: Carbon steel for mechanical structure
  • Painting: Epoxy powder painting

It is a differentiated product from the existing Grooved joint method, and it is a Grooved joint in which pipes and fittings can be easily fastened without breaking down bolts/nuts and rubber rings.

The Model AJ550R is a ready to install rigid coupling for general piping applications where rigidity is required, including valve connections, mechanical rooms, risers, and long straight runs.

AJ550R couplings should always be installed so that the coupling bolt pads make metal to metal contact.
