AJ550F

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 Flexible 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 AJ550F is a ready to install Flexible coupling for general piping applications where rigidity is required, including valve connections, mechanical rooms, risers, and long straight runs.

AJ550 F couplings should always be installed so that the coupling bolt pads make metal to metal contact.
