  • Patent number: 10428985
    Abstract: A fluid system swivel joint includes a body and a tail rotatably connected together and which partially define a fluid passageway. The tail has an integrally formed flange for connecting to other fluid conduits. A counterbalancing mechanism is disposed within the fluid passageway. The counterbalancing mechanism has a selectively adjustable level of tension that adjusts the amount of force required to rotate the tail relative to the body. At least a portion of the counterbalancing mechanism can be selectively inserted into or removed from the fluid passageway through an opening in the body. The opening in the body can be closed off with an end plate. A swivel assembly rotatably connects the body to a fluid conduit so that the body can rotate relative to the fluid conduit. The swivel assembly includes a collar fixedly and selectively connectable to the body, and a flange body rotatably connected to the collar.
