A fluid connection apparatus, in which a carrier body and washer configuration are overmolded together, is configured for use in a fluid transfer assembly. The carrier body may be generally U-shaped, having two substantially parallel portions connected by a bridging portion. Each substantially parallel portion of the fluid connection apparatus includes a washer configuration including one or more washers. The fluid connection apparatus may be used to connect a fluid line fitting to an apparatus intended to provide or receive fluid through the fluid line, using a connector having a fluid passage formed therein. The fluid line fitting is placed between the two substantially parallel portions, and a connector having a fluid passage formed therein is inserted through one side of the fluid connection apparatus, through the fluid line fitting, and through the other side of the fluid connection apparatus. The fluid connection apparatus may include stabilizing features, such as ribs in the bridging portion or enlarged radii, to protect against distortion and breakage.

A torque link assembly may comprise an upper torque link, a lower torque link, and a torque link pin. The upper torque link may define an upper hydraulic fluid channel. The lower torque link may define a lower hydraulic fluid channel. The torque link pin may fluidly couple the upper hydraulic fluid channel to the lower hydraulic fluid channel.

Described are systems and methods for a hydraulic swivel. The hydraulic swivel receives fluid flow in one direction and, in certain configurations, changes the direction of the fluid flow to a second direction before the fluid leaves the hydraulic swivel. The hydraulic swivel includes a first banjo, a second banjo, and a base. The banjos of the hydraulic swivel are configured to be repositioned.

The disclosure relates to an adapter (200) for converting a naturally-aspirated flotation cell (10) to a forced-gas flotation cell without replacing the naturally-aspirated flotation cell reducer (21) with a specialized conversion reducer (103). The adapter (200) is designed to be located below the naturally-aspirated flotation cell reducer (21) and at a location along the drive shaft. The adapter (200) comprises an outer static casing (201) having a forced gas inlet (210); an inner rotating spanner (204) having at least one port (205) therein; sealing means (203, 224, 225, 226) provided between the static casing (201) and the spanner (204); and, a chamber (213) formed between the outer static casing (201) and the spanner (204). Related methods and apparatus incorporating the adapter (200) are further disclosed.
