A hydraulic adapter unit includes a hose connecting member and a pipe member. The hose connecting member is a substantially cylindrical hose connecting member, and includes: a hose fixing portion positioned at one end side of the hose connecting member and to which the hose is fixed; a first combining portion positioned at the other end side of the hose connecting member; and an intermediate portion linking the hose fixing portion and the first combining portion. The pipe member includes: a substantially tubular pipe body; a second combining portion disposed at the one end side of the pipe body and separably combined to the first combining portion of the hose connecting member; and a flange portion disposed at the other end side of the pipe body and formed so as to project outward in the radial direction of the pipe body and fixed to a hydraulic device.

A crimp coupling includes a crimping ferrule for connecting a hose to a fitting. The fitting includes an outwardly projecting stop collar and a groove which extends circumferentially around the fitting at a constant axial distance to the stop collar. The crimping ferrule, which can be slid onto the fitting, includes a flange, a tapering hinge section, and a cylindrical section. A distance between the stop collar and the groove of the fitting is dimensioned such that the flange, when abutting the stop collar, has a lower edge facing away from the stop collar above the groove. Due to a diameter reduction of the cylindrical section and the tapering hinge section, during crimping, the flange is pivoted such that the lower edge of the flange is turned into the groove by the pivotal movement of the flange.

A hydraulic system has a fluid path which connects two system components fluidically to one another and which comprises a hydraulic hose. It is known to form a fluid path between two components of a hydraulic system, for example between a pump and a control block, by a single hydraulic hose which is designed in accordance with the maximum volume flow and the maximum pressure. A hydraulic hose for large volume flows and high pressures is disproportionately expensive relative to a hydraulic hose for smaller volume flows and, on account of its larger internal and external diameters, has a larger minimum bending radius than a hydraulic hose for smaller volume flows. In order to provide a cost-effective and compact structure, a hydraulic system according to the disclosure has the fluid path formed by at least two hydraulic hoses arranged fluidically parallel to one another.

A shrink-fit ring, the two circumferential edges (10) of which are flanged, makes it possible to use thinner band thicknesses without the risk of buckling owing to its greater intrinsic strength. The circumferential edges (10) end in limbs (16) which point radially outwards and enclose an angle of approx. 70° to 90° with an unflanged centre portion (13) of the ring that is located axially further inwards. The flanging results in an extension of the diameter of the ring edges, wherein the ring edge regions (14) are bent outwards in a rounded manner and the edge surfaces (11) run at an angle of preferably approx. 0° to approx. 20° with respect to the ring axis (12).

A hydraulic coupling system is configured to couple a hydraulic hose to a hydraulic cylinder and includes: a compressive adapter assembly including: a first adapter portion configured to receive a portion of the hydraulic hose, and a second adapter portion configured to engage an inlet tube of the hydraulic cylinder, wherein a first tube portion of the inlet tube of the hydraulic cylinder is configured to be received within a portion of the hydraulic hose; and a compressive sleeve assembly configured to engage the compressive adapter assembly and radially compress the first adapter portion of the compressive adapter assembly onto an outer surface of the portion of the hydraulic hose, thus compressing an inner surface of the portion of the hydraulic hose onto the first tube portion of the inlet tube of the hydraulic cylinder.

An outlet structure of a faucet valve seat, has a valve seat and a sleeve pipe, wherein the valve seat forms a sleeve hole, the sleeve pipe is used to set an outlet pipe, and the sleeve pipe is sleeved in the sleeve hole. The sleeve pipe penetrates through a plug hole, and one end of the outlet pipe is inserted into the plug hole, such that a long axis is parallel to the central axis of the valve core, and a central axis of the plug hole forms an included angle with the long axis as θ. The valve seat can be selected by the sleeve pipe with the corresponding angle of the plug hole according to the needs of the outlet pipe, and meet the diversified demand of the outlet pipe elevation angle.

A fitting for connecting pipes, in particular flexible pipes, includes a first tubular element provided with a first inlet/outlet opening and defining at its interior a first duct, and a second tubular element provided with a second inlet/outlet opening and defining at its interior a second duct. The two tubular elements are connected to each other in a manner such that the first and the second duct are in communication. The fitting includes a first bushing associated with the first tubular element in order to externally surround it and create an annular housing, which can operate in an insertion configuration, in which it allows the insertion of a pipe in the annular housing, and a clamping configuration, in which it presses and locks the pipe in a fluid-tight manner. The fitting includes a first bushing-holder externally associated with the first tubular element and configured for mounting the first bushing so that it defines the annular housing, including a seal portion externally wound around and in contact with a seal sector of the first tubular element. The seal portion is interposed between a portion of the pipe inserted in the annular housing and the seal sector, and attains a fluid-tight gasket when the first bushing is in clamping configuration, preventing the leakage of fluid between the first duct and the exterior of the fitting.

A connector assembly may include an elastomeric connector comprising an approximately perpendicular flange at a distal end thereof and an opening therethrough; and a rigid compression fitting having an opening aligned with the opening of the elastomeric connector. The connector assembly may be used with a converter hose. Related methods include attaching the converter hose to a shower head, faucet or spigot.

The present invention relates to a multipurpose hose clamp. The hose clamp is capable of rotating laterally in a 360-degree orientation in clockwise and counterclockwise directions. The multipurpose clamp includes a round, flat, thin, single-gear band, and a clamping device. The clamping device or screw cage is separable from the band. A screw is configured to twist or turn into the clamping device and engages the slots disposed on the band to increase or decrease a diameter of the hose clamp. The multipurpose clamp can be applied to any type of hose, for example, water hoses, automobile hoses, radiator hoses, air vent hoses, etc. The screw cage is designed to rotate 360-degrees in either clockwise or counterclockwise directions.

A compression collar is manufactured for use in reinforcing an interference fit between an end of a pipe and a fitting. A precursor form is injection molded using a cold-expansion material. The precursor form has a tubular body with an initially closed axial end and a bore that is initially blind formed in the other axial end. Material is removed from the initially closed axial end of the tubular body of the precursor form to form an opening in the initially closed axial end that connects to the bore thereby forming the compression collar. The opening has an inner periphery with a profile in axial cross section that is different than any profile in axial cross section of an inner periphery of the bore. The collar formed may lack knitlines and may include tabs formed during the removal step which help to position the collar on a pipe.
