Devices for coupling to a first and second conduit and methods of manufacturing the same. The device may include a first member defining a channel having a first opening and second opening, and one or more threads located on an inner surface of the channel at the second opening, the first member configured to receive the first conduit at the first opening and the second conduit at the second opening, and the one or more threads engages one or more threads of the second conduit. The device may include a second member circumferentially disposed around a periphery of the first member and axially extending therefrom, the second member including an inner diameter configured based on an outer diameter of the second conduit to enable the second member to form a seal around the second conduit when the second conduit fully engages the first member.

A collar for applying a radial compressive force to an outer surface of a tube and a tube assembly including the collar and the tube.

A polymer pipe has a length between a first end and a second end. The length and the first end have a first diameter and the second end is a belled end having a second diameter larger than the first diameter. An insert device is received or pre-installed within the second end and has an annular body with a seal part coupled to the annular body and a spline groove formed in the annular body and facing radially inward. Another polymer pipe is inserted in the belled end to form a pipe joint assembly and has a mating spline groove on the outer surface. The spline groove and mating spline groove axially align and receive a spline therein to axially interlock the two polymer pipes to form a pipe joint assembly.

A high-pressure hose includes an inner tube, a first braided layer and a second braided layer. The inner tube defines an axial direction and a circumferential direction. The first braided layer includes a plurality of first braiding yarns and a plurality of first imaginary axes. Each of said first imaginary axes is passed through a plurality of first intersections of the plurality of first braiding yarns. The second braided layer is sleeved around the first braided layer and includes a plurality of second braiding yarns and a plurality of second imaginary axes. Each of said second imaginary axes is passed through a plurality of second intersections of the plurality of second braiding yarns. The plurality of first imaginary axes are at least partially misaligned with the plurality of second imaginary axes in a radial direction of the inner tube.

A piping system including each of a first pipe comprising a bell end and a groove formed in the bell end and a gasket positioned within the groove; a second pipe comprising a spigot end, the spigot end position within the bell end of the first pipe and in contact with the gasket; a bell end reinforcing device positioned external to at least a portion of the bell end of the first pipe, the bell reinforcing device providing structural reinforcement to an exterior surface of the bell end. The piping system may also comprise a pipe stop where the pipe stop mechanically interfaces with the bell reinforcing device to inhibit relative axial movement between the first pipe and second pipe, such as by a dovetail connection.
