A flexible duct includes a hollow tube shape, at least one end, a first circumferential attachment and a second circumferential attachment integral to the at least one end, wherein the first circumferential attachment and the second circumferential attachment are each configured to independently mechanically couple the at least one end around a first inlet or a first outlet, and wherein the first circumferential attachment and the second circumferential attachment are different. A method includes providing a flexible duct, selecting one of the first circumferential attachment or second circumferential attachment of the flexible duct, and mechanically coupling the selected first circumferential attachment or second circumferential attachment around the first inlet or first outlet. A connector for a flexible duct includes a hollow tube shape extending between a first connector end and a second connector end and a first circumferential attachment and second circumferential attachment integral to the at least one end.

An adapter for putting two incompatible medical systems in fluid communication with each other. The adapter may have a continuous outer diameter and may include two segments: a first segment composed of a rigid material and including a first portion and a second portion, the first portion having a continuous outer diameter and the second portion defining one or more flanges, the first segment defining a first passage therethrough; and a second segment composed of a flexible material and coupled to the first segment, including a first portion and a second portion. The first portion of the second segment may have an inner surface configured to surround the flanges of the second portion of the first segment, and the second portion of the second segment having a tapered inner surface, the second segment defining a second passage therethrough that is continuous with the first passage.

The invention described herein relates to reservoirs within appliances. The present invention includes a reservoir made of a length of reservoir tubing. In particular embodiments, the length of the reservoir tubing is formed in an overlapping circular portion and conforms to the available space requirements within an appliance. Particular embodiments of the present invention include reservoirs, reservoir systems including a reservoir, processes for forming a reservoir, and processes for forming the aforementioned reservoir systems.

An exemplary duct system includes a rigid duct member, a first duct connector connected to the rigid duct member, a first sealing member disposed between the rigid duct member and the first duct connector, a flexible duct, a second duct connector connected to the flexible duct, and a second sealing member disposed between the first duct connector and the second duct connector. The first duct connector is assembled to the second duct connector to compress the second sealing member and form a seal between the first duct connector and the second duct connector and thereby form a seal between the rigid duct member and the flexible duct.

A connector for a flexible non-metallic conduit is provided. The connector may include a gland nut for receiving the conduit, and a gland ring within the gland nut. The gland ring may be sized to extend around the conduit. The connector may further include a body threadably secured to the gland nut, and a ferrule disposed within the body, wherein the ferrule includes a first keying feature coupled to a second keying feature of the body to cause rotation therebetween, and wherein the ferrule is inserted partially into the conduit. In some embodiments, the gland nut is not directly physically coupled to the conduit, so the gland nut may slide over the conduit towards/away from the body. In some embodiments, during assembly, the body and the gland nut may be rotated together to cause external threading of the ferrule to engage an inner wall of the conduit.

A multi-fitting rotatable fluid connection apparatus comprising a fluid entry fitting and first and second fluid discharge fittings. The fluid entry fitting comprises a first end connector threaded for attachment to a fluid source, and first and second distribution connectors. The first fluid discharge fitting has a first intake connector which receives fluid from the first distribution connector. A first rotation member is coupled between the first intake connector and the first distribution connector such that the first fluid discharge fitting is rotatable about a first axis of rotation. The second fluid discharge fitting has a second intake connector which receives fluid from the second distribution connector. A second rotation member is coupled between the second intake connector and the second distribution connector such that the second fluid discharge fitting is rotatable about a second axis of rotation.

A tubing assembly for fluid delivery to a bearing system may comprise a fitting having an inner surface defining an inner flow path and having an outer surface defining a first mating surface. A first tube may be coupled to the fitting. The fitting may be disposed within a bearing housing of the bearing system. The bearing housing may include a second mating surface in sealing contact with the first mating surface of the fitting.

A support sleeve reinforces yielding pipes, in particular plastic pipes, in the clamping region of a fastening bracket. The invention is based on the object of improving a support sleeve of the type mentioned at the outset so that the support sleeve remains securely in place in the interior of the plastic pipe even in the case of diameter variations of the plastic pipe without any complex preliminary deforming being necessary such that the support sleeve is capable of being fixed in the pipe end by way of a simple snap-fit. The support sleeve is configured as a pipe portion, wherein the pipe portion has notches so that each notch has a resilient tongue-shaped portion which at one side is resiliently connected to the support sleeve and which at the end thereof that is opposite the connection point to the support sleeve, protrudes radially beyond the external diameter of the support sleeve, pointing outward such that the tongue-shaped portion has a pawl-type shape.
