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.
