A tube connection system includes a holder holding first and second fluid-path members, a heater, and an extractor. Each fluid-path member includes an internal channel along a first direction, a fluid path end at an end of the internal channel and capable of being fusion-bonded, and a sealing element of higher thermal conductivity than that of the fluid path end for covering the fluid path end. The holder holds the first and second fluid-path members with respective sealing elements facing and being pressed against each other. The heater heats the sealing element of each fluid-path member. The extractor pulls out the sealing element of each fluid-path member in a second direction orthogonal to the first direction.

A probe for a closed transfer system, the probe including a probe body and a probe tip. The probe body defines an inlet, an outlet, and a plurality of channels. The outlet is in fluid communication with the inlet via at least one of the plurality of channels. The probe tip is located at a top end of the probe body and defines a first passageway. The first passageway is in fluid communication with at least one of the plurality of channels. The probe body is configured to be slidably moveable within a coupler body between a first position where the probe tip is received within the coupler body and a second position where the probe tip extends at least partially away from the coupler body to open a fluid flow path through the coupler body.

Aspects of the present disclosure relate to crane systems and pump manifold systems, and related methods, for pumping operations (such as frac operations). In one or more embodiments, a pump manifold system includes a plurality of connection blocks, a plurality of conduits coupled between the plurality of connection blocks, and a crane system. The crane system includes a base, and a first crane coupled to the base and configured to extend relative to a first side of the at least one conduit. The first crane is pivotable relative to the at least one conduit.

A valve and coupling for joining pipe elements has a valve body captured in a central space defined by a plurality of coupling segments attached to one another end to end. The inner surface of the valve body defines a bore. A liner on the inner surface surrounds the bore and forms a seal with a valve closing member. Circumferentially arranged projections on the segments engage and center the valve body within the central space. The liner has lobes that extend axially in opposite directions. The lobes are compressed between the segments and the pipe elements to form a fluid tight seal when connection members are tightened to draw the segments toward the central space and into engagement with the pipe elements.

In some examples, a connector assembly configured to connect a tube to a peritoneal dialysis cycler comprises: a connector piece having a bore, wherein a proximal end of the bore defines an opening in a proximal portion of the connector piece configured to receive and deliver fluid from and to the cycler; and a connector body having a bore, wherein a proximal end of the bore defines a cavity in a proximal portion of the connector body configured to receive a distal portion of the connector piece to position the distal end of the bore of the connector piece in fluid communication with the proximal end of the bore of the connector body. The distal portion of the connector body comprises a tubular portion configured to form an interference fit with the tube. A collar of the connector body is configured to grip an outer surface of the tube.

Provided is a hose including a first connector assembly including a regulator assembly, a second connector assembly, and a hose assembly coupled to the first and second connector assemblies. The hose assembly includes an inner hose member having first and second ends, an outer hose member having first and second ends, a first hose connector assembly coupled to the first ends of the inner hose member and outer hose member and the first connector assembly, and a second hose connector assembly coupled to the second ends of the inner hose member and outer hose member and the second connector assembly.
