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.

Housing: Ductile Iron to ASTM A536, Gr. 65-45-12
Surface Finish: Epoxy Coating
Rubber Gasket: Grade EPDM approved under NSF/ANSI 61.
Bolts & Nut: CS for machine structural use.
