AJS720G

The grooved joint method is simpler and faster than welding in the field. To relieve the stress of the piping, change the orientation of the piping or use the joint to secure the piping.

  • Industrial standard: KS, JIS, ANSI
  • Grooved Outlet type
  • Joint material: Spherical graphite cast iron(ASTM A536, GCD450)
  • Gasket Material: EPDM
  • Bolt/nut material: Carbon steel for mechanical structures
  • Painting: Epoxy Powder Painting

The grooved joint method is simpler and faster than welding in the field.
To relieve the stress of the piping, change the orientation of the piping or use the joint to secure the piping.

The Model AJS720G Outlet Coupling combines the features of a coupling and a reducing outlet. The AJS720G is a joining device with an integral reducing outlet, eliminating the need for a mechanical tee or a reducing tee and couplings. The AJS720G 1s available with grooved, male threaded or female threaded outlets. The AJS720G coupling is recommended for fire sprinkler services and other applications up to 300 psi (20 Bar) depending on the size and schedule of pipe being used. All Model AJS720G couplings are comprised of an upper and lower ductile iron housings segment, EPDM rubber gasket and plated track bolts & nuts.

AJS720G couplings should always be installed so that the coupling bolt pads make metal to metal contact.
