A full flow hose fitting formed from an assembly process that pushes the fittings into the end of the hose rather than using an internal or external crimped ferrule to secure them.

A coupling assembly having first and second sleeves configured to be tightened to a fluid conduit, a radial-split gasket configured to be positioned between the sleeves and the fluid conduit and having an outer gasket layer and a separate inner gasket layer configured to be selectively disengaged from each other, an inner circumferential surface of the outer gasket layer and/or an outer circumferential surface of the inner gasket layer comprising a plurality of circumferentially spaced retaining protrusions interfacing between the inner and outer gasket layers, each of the retaining protrusions having a separation portion and an engagement portion connected to the other gasket layer by a gasket layer connection such that the engagement portion will separate at the separation portion under an applied separation force prior to the engagement portion separating at the gasket layer connection.

A water heating device equipped with a housing, a fan and a chamber arranged in the interior of the housing, and screws. The housing has first and second side plates which oppose one another in a first direction and extend from the ends of a back plate along a second direction intersecting the first direction. An opening part is provided in the housing on the side opposite the back plate in the second direction. The fan has a discharge opening, a first flow passage extending along the first direction, and a first flange. The chamber has an intake opening, a second flow passage extending along the first direction, and a second flange. The first and the second flanges are secured by screws. In a planar view, the center axis of the screws is slanted such that a head portion is closer to the opening part than the tip-end portion.

A formed pipe end-section of a pipeline for connecting the pipeline at an end includes: an annular bead with a first abutment face facing away from the end of the pipeline and a second abutment face facing towards the end of the pipeline; a chamfer reducing a diameter of the pipe end-section from the annular bead towards the end of the pipeline; and a radial recess for accommodating a sealing ring. The chamfer extends at least between the annular bead and the radial recess.

[Problem] To provide a pipe joint allowing reliable connection to a pipe P without flaring.

[Means of solving problem] The pipe joint includes a flare joint body 1F, a cap nut 2, and a stop ring 3. A curved pressure-contacting slope surface 32 of the stop ring 3 contacts a slope surface 5 with reduced-diameter tip of the flare joint body 1F under pressure to establish sealing by means of mutual contact between metallic surfaces. The pipe P is grasped in a tightly pressure-contacting state using a back tooth and a front tooth formed at a tip head 37 of a substantially cylindrical thin part 35 of the stop ring 3.

A fluid transfer connector securely connects a port fitting of a fluid device to a fluid hose. The fluid transfer connector includes an attachment member attachable to the port fitting of the fluid storage device. The fluid transfer connector further includes a hose adapter including a housing with a seal that wipes and sealingly engages the port fitting when the hose adapter is engaged to the attachment member.

A fluid connector in a fluid joint assembly such as in a machine hydraulic system includes a connector body having a stem with a seal face extending circumferentially around a connector axis at a backup sealing location. A non-metallic seal is upon the stem and extends circumferentially around the connector axis at a primary sealing location. The fluid connector also includes a swivel nut including threads and a snap retainer and supported for rotation upon the stem. The fluid connector can establish a primary sealing state by way of hand installation, and can be torqued to a backup sealing state to provide a robust metal-to-metal seal.

A union connection common in connecting pipelines in various industries comprises a threaded female pipe end, a male pipe end insertable into the female pipe end to form a sealed connection, a plurality of shaped ring segments and a threaded collar in which the shaped ring segments are placed in a shaped groove on the male pipe and positioned in the threaded collar. The threaded female pipe end is then threaded onto the threaded collar, the threads each being clocked so as to press the collar against the male pipe using the ring segments and into a sealed connection with the female pipe. A pin inserted through a pin hole in the collar and into a pin recess in the female pipe end holds the parts in place. The pin hole and pin recess are positioned relative to the clocked threads of the collar and female pipe.
