This document describes fluid handling couplings. For example, this document describes fluid handling couplings that include manually openable valves and that are configured for aseptic fluid handling usage. In some embodiments, the valves are manually openable by rotation of a collar of the fluid handling couplings.

A coupling includes a male adapter and a female adapter, and may include a nut and a sleeve. In embodiments, the male adapter includes a male adapter inner diameter, and may include threads. The female adapter includes a female adapter outer diameter. The nut or other formation may be configured to engage at least a portion of the male adapter. In embodiments, one or more contact points may be provided between the female diameter outer diameter and the male adapter inner diameter, and the female adapter outer diameter or the male adapter inner diameter may be configured to be out-of-round. The male adapter may include a shoulder and the sleeve may cover the shoulder in connected configuration. Methods for forming a coupling are also disclosed.

A connector is provided comprising first and second hollow bodies with a fluid transfer member, slidably arranged between the first and second hollow connector bodies.

Component connector for connecting cylindrical components includes an elastic sleeve which surrounds the components, the elastic sleeve can be braced, a radially deformable fixing sleeve is provided which encloses elastic sleeve. Elastic sleeve is braced via radial deformation of fixing sleeve in a perpendicular direction to a longitudinal axis of fixing sleeve, and at least one clamping ring is provided for radially deforming fixing sleeve. Fixing sleeve has a profiled outer wall and clamping ring has an oppositely profiled inner wall so clamping ring can be pushed concentrically onto fixing sleeve in an accurately fitting manner, during a relative rotation of clamping ring, placed in an accurately fitting manner, in a closing direction, the fixing sleeve can be deformed radially inwardly by the surface profiling; and, during a relative rotation of clamping ring counter to the closing direction, the surface profiling prevents any rotation.

A connector having a male component and a female component. The male component has a first tubular section, a second tubular section, and a midsection between the first tubular section and the second tubular section. The female component is connected to the second tubular section of the male component upon relative rotational movement between the male component and the female component and disconnected from the second tubular section of the male component upon relative rotational movement between the male component and the female component in a direction opposite to the direction when the male component and the female component are being connected. The female component has a bearing surface bearing against the midsection of the male component in a first position of the bearing surface and is spaced from the midsection of the male component in other positions of the female component.

A connector assembly includes a first connector, a compression member, a retainer, and a second connector. The first connector includes a first coupling portion, a proximal opening, and an annular inner surface extending from the proximal opening. The compression member includes an inner surface and an outer surface. The outer surface is configured to sealingly engage the annular inner surface of the first connector. The retainer includes a ring portion and a plurality of teeth. The ring portion includes a proximal end and a distal end. Each of the plurality of teeth extends from the distal end and is configured to engage the compression member. The second connector includes a second coupling portion and an engagement surface. The second coupling portion is configured to engage the first coupling portion. The engagement surface is configured to engage the proximal end of the retainer.

Air induction systems are for an internal combustion engine. The air induction systems comprise an air intake plenum that conducts intake airflow to an air cleaner for cleaning prior to combustion in the internal combustion engine. The air intake plenum is movable with respect to the air cleaner between an open position separated from the air cleaner and a closed position connected to the air cleaner. A bellows connects the air intake plenum to the air cleaner when the air intake plenum is in the closed position. The bellows has an upstream first end that seals with the air intake plenum and a downstream second end that seals with the air cleaner.

A quick connector includes a valve body and a rotatable ring fitting over the valve body. The rotatable ring is rotatable with respect to the valve body. When a sealing member of the rotatable ring is rotated to a full open position, an exit end and an entrance end of the valve body are both encompassed by an opening of the sealing member and communicating with each other. When the sealing member is rotated from the full open position to a full close position, one of the exit end and the entrance end is moved out of the opening and blocked by the sealing member, so that the entrance end and the exit end do not communicate with each other.
