A multi-manifold connector is provided. The multi-manifold connector includes a base, a hot water connector, and a cold water connector, where the hot water connector and the cold water connector are arranged on the base; the hot water connector is provided with a water inlet; the cold water connector is provided with a water outlet; a bottom of the base is provided with multiple first water pipes and multiple second water pipes; the multiple first water pipes run through the base and are communicated with the hot water connector; and the multiple second water pipes run through the base and are communicated with the cold water connector.

Provided is an adapter configured for use with an aerosol can spray nozzle and an extension tube. The adapter is configured to fit onto an extension tube and to receive a second extension tube to provide a more rigid and fluidly secure connection between the extension tubes. The adapter includes a portion for a first extension tube and a second extension tube portion. Each extension tube portion includes an inner channel extending therethrough, and is sized and configured to allow the extension tube to be insertable therein to create friction-tight engagement between the extension tube and the adapter.

A coupling member for a blind mate fluid coupling includes a housing and a valve body that is self-centering and alignable relative to the housing. The valve body may include at least two radial shoulder portions or abutments that are configured to engage at least two corresponding radial abutments of the housing to improve self-centering when in a decoupled state. A biasing member may urge the valve body abutments against the corresponding housing abutments to compensate for misalignment and/or provide self-centering in both a decoupled and mated state.

A connecting assembly for operatively and fluidly connecting at least first and second hose segments together. The connecting assembly includes at least one insert portion, and corresponding bulge(s), securing device(s) and fluid passage(s). The securing device is removably mounted onto and displaceable about a portion of a given length span of the insert portion, and configured for operation between a first release mode, where the securing device being is drawn away from the bulge and thus an extremity of the hosing segment is releasable, and a second connecting mode, where the securing device is removably and selectively displaced over an outward overlapping of the extremity of the hosing segment extending over the bulge, so as to securely maintain said extremity of the hosing segment in place, operatively against the bulge and thus, prevent the first extremity of the first hosing segment from being removed from the bulge.

A bidirectional airflow attachment hose may include an elastomeric connector and a rigid compression fitting having an opening aligned with the opening of the elastomeric connector. Related methods include attaching the bidirectional airflow attachment to a nozzle.

A pipeline mounting head for a vehicle, comprising a mounting plate, two branch pipelines located on one side of the mounting plate, and a main pipeline located on the other side of the mounting plate and communicating with the branch pipelines, where a snap-fit member is provided on the mounting plate, and is located on the same side of the mounting plate as the branch pipelines. The snap-fit member is arranged on the mounting plate, so that the vehicle pipeline mounting head can be easily fixed to a vehicle, has a simple mounting structure, and is easy to operate. Further disclosed are a pipeline structure and a vehicle having the pipeline structure.
