A converter hose includes a self-sealing connector coupled to a hose. Related methods include attaching the converter hose to a shower head, faucet or spigot.

A limb for a breathing circuit manufactured from very thin walled polymer materials has an elongate axial reinforcing spine lying freely inside the conduit and fixed to each end connector. The spine is laterally compliant but axially stiff. The spine provides resistance to tensile and compressive loads on the conduit, including that induced by prevailing internal pressures.

Pliable-wall air ducts with internal expanding structures are disclosed. An example air duct system includes an air duct including a pliable sidewall. The example air duct system further includes a shaft including a first end and a second end. The shaft extends in a longitudinal direction along a length of the air duct with the first end coupled to a first point of the air duct and the second end coupled to a second point of the air duct. The first point is downstream of the second point. The pliable sidewall is to be held in tension in the longitudinal direction between the first and second points in response to compression in the shaft between the first and second ends.

A hose can include an inner tube that can form a flow path and an inner fiber layer that can be formed around an outer surface of the inner tube. The hose can further include an intermediate fiber layer that can be formed around the inner fiber layer, and an intermediate fiber layer that can be formed around the inner fiber layer. An outer layer can be formed around the intermediate fiber layer. The inner fiber layer, the intermediate fiber layer, and the outer fiber layer can be formed from support thread applied with greater than about 10 pounds (lbs) of tension. The support thread of the inner fiber layer, the support thread of the intermediate fiber layer, and the support thread of the outer fiber layer can include aramid fibers.

A water pipe includes a pipe body (1), a woven layer (2) sleeved around the pipe body (1), a first joint assembly (3) arranged at one end of the pipe body (1) and secured to the pipe body (1), and a second joint assembly (4) arranged at another end of the pipe body (1) and secured to the pipe body (1); the woven layer (2) includes bamboo charcoal fibers and polypropylene filaments. The woven layer (2) is sleeved around the pipe body (1) and is not connected with the pipe body (1), and the woven layer (2) includes bamboo charcoal fibers and polypropylene filaments. Bamboo charcoal fibers have the functions of resisting bacteria and removing peculiar smell and can effectively prevent the generation of bacteria on the water pipe and the emission of peculiar smell when the water pipe is used in humid outdoor environments.

A hose nozzle assembly which is capable of heating water comprising an internal heating chamber with at least one heating element. The hose nozzle assembly is able to heat water from a common garden hose with the ability to control both flow rates and temperature.
