Systems, apparatus and methods for providing air and water to hot tub jets. The present teachings include jet assemblies, manifold assemblies, and related components, as well as methods of assembling hot tubs involving these components. In some cases, the present teachings describe the use of dual extrusion tubing to route air and water through adjacent, connected fluid conduits. In some cases, the present teachings describe a press-and-click method of connecting various components.

The present application discloses novel systems for conducting the filtration of blood using manifolds. The manifolds integrate various sensors and have fluid pathways formed therein to direct fluids from various sources through the requisite blood filtration or ultrafiltration system steps.

An encapsulated valve system includes a first housing portion having a first facing surface, the first facing surface comprising a plurality of branch pathways formed as a recess within the first facing surface. The valve system further includes a second housing portion having a second facing surface, the second facing surface comprising a plurality of branch pathways formed as a recess within the second facing surface. A disposable conduit is configured to be interposed between the first and second housing portions and disposed within the recess of the first facing surface and the recess of the second facing surface. The disposable conduit is thus sandwiched between the first and second facing surfaces. A plurality of pinch valve actuators are mounted on one or both of the first housing portion and the second housing portion, the plurality of pinch valve actuators configured to pinch the disposable conduit at selective branch pathways.

A thermally responsive fluid control valve includes a thermally responsive actuating assembly and a body having an inlet, at least one outlet, and a valve seat formed internally of the inlet. An axially translating sealing assembly is supported in a seated position against the valve seat by the thermally responsive actuating assembly and the sealing assembly has an unseated position upon operation of the actuating assembly. The sealing assembly includes a sealing member having an impact surface for redirecting fluid from the inlet to the at least one outlet and a rod member with an outer surface in a surface engagement with the opening of a cover plate and/or the actuating assembly to orient the sealing member such that the impact surface directs fluid flow to the outlets.

An apparatus includes a production tool and a pipe connected to the production tool. The pipe includes an inner pipe formed of a metal-free material, an outer pipe encircling the inner pipe, and an inlet connected to a channel between the inner pipe and the outer pipe. The apparatus further includes a chemical supply system connected to the pipe. The chemical supply system is configured to supply a chemical through a channel encircled by the inner pipe to the production tool.
