Construction of a sealed connection between an elastomeric or synthetic polymer flexible pipe or hose and a metallic coupling member. The coupling member surrounds an armor layer at a free end of the flexible pipe or hose. A sealing area is defined by a recessed portion of the pipe coupling into which a sealing material is introduced. An inner liner layer of the flexible pipe or hose may extend into the sealing area where it is bonded to the sealing material. The sealing material and the inner liner layer may each be comprised of a semi-crystalline thermoplastic material. Furthermore, a reinforcement material may be provided in the inner liner layer.

An extensible-retractable helically reinforced hose is formed by helically wrapping a freshly extruded bead of thermoplastic material about a rotating mandrel to form a helical array of spaced reinforcing coils, and by helically wrapping a freshly extruded thin yet wide web of thermoplastic material so edge regions of the wide web are placed onto and bond continuously with the peripheries of each adjacent pair of the reinforcing coils, with a leading edge region of each new wrap of the web overlying and bonding to a trailing edge region of a prior web wrap. Central portions of each web wrap extend radially inwardly and are sandwiched between adjacent reinforcing coils when the hose is retracted to a minimal axial length.

A hose nozzle assembly which is capable of heating water comprising an internal heating chamber with at least one heating element. The hose nozzle assembly is able to heat water from a common garden hose with the ability to control both flow rates and temperature.

A composite tube includes a first layer including a thermoplastic polymer having a Tg of not greater than about 160° C. and a second layer adjacent to the first layer, the second layer including an extruded silicone material. Further included is a method of forming the composite tube which includes providing a first layer including a thermoplastic polymer having a Tg of not greater than about 160° C.; receiving, by an extrusion system, a silicone material; forming, by the extrusion system, a second layer including the silicone material adjacent to the first layer; and irradiating the silicone material with a radiation source to substantially cure the silicone material.

The invention involves a modular elevated hose hanger system. The system includes a vertical support member suitable for insertion into a ground surface for elevating the hose hanger and preventing unwanted rotation of the hose hanger about the vertical axis of the vertical support member. The hose hanger is constructed of a cylindrical segment having features for interlocking with the vertical support member. A modular face plate cooperates with the cylindrical segment to provide structural support to the cylindrical segment while being easily removable and replaceable.

A four-layer-structured water passing device is provided, in which a first sleeve and a second sleeve are disposed between an elastic inner tube and an outer cloth sheath. When the water passing device is connected with a pressurized water source, the first sleeve can quickly eliminate or reduce the impact wave strength when receiving a strong expansion impact from the elastic inner tube, such that the first sleeve can gently transmit the fluctuation to the second sleeve, and the second sleeve extends the outer cloth sheath to the limit length, so as to avoid damage caused by frequent direct contact friction between the elastic inner tube and the outer cloth sheath. The water passing device is also configured to avoid permanent deformation and abrasion at the joint position between the elastic inner tube and the outer cloth sheath, and thus prolong the service life of the water passing device.
