A cable conduit transition including a longitudinal axis, a lower portion having a semicircular shape around the longitudinal axis and two lower portion terminating ends, an upper portion having a semicircular shape around the longitudinal axis and two upper portion terminating ends, and wherein the two lower portion terminating ends are offset from the two upper portion terminating ends.

A hopper tee having a horizontal portion through which granular material is unloaded from a tank trailer or hopper car, the hopper tee integrally forms a vertical segment, that secures with the bottom of the hopper, to provide for unloading of granular material for usage or storage. The upper front portion of the tee, as it transitions from its vertical segment to the horizontal flow path has secured or cast therewith a ledge, that provides for accumulation of the unloading granular material therein, to function as a wear pad to resist against abrasion and accelerated wear out of the tee, at that location, during prolonged usage.

A method of rotationally molding a large-diameter pipe fitting, the wall structure of which is characterized as having a generally smooth interior surface and an exterior surface that is defined by a plurality of axially-spaced circumferentially extending ribs which are monolithically formed and homogeneous with the smooth interior surface of the fitting. The fitting is seamless and modularly designed with integral coupling elements at each terminal end, and with a ribbed wall structure profile capable of withstanding the loads typically found in buried applications with watertight performance requirements, where such ribbed wall structure meets the following dimensions and dimensional ratios: Rib Sidewall Angle (95-105 degrees); Bottom/Top Rib Thickness Ratio (1.80-2.80); Pitch/Rib Height Ratio (1.50-1.95); Rib Height/Fitting Diameter Ratio (0.04-0.09); and Avg. Rib Thickness/Rib Height Ratio (0.28-0.40).

Fittings include a conduction section, a coupling groove and an access port. One fitting also includes a socket section. The conduction section may be connected to receive permeate fluid from a reverse osmosis pressure chamber and the socket section may be connected in parallel with other fittings to form a permeate collection manifold system.

A resin pipe joint includes a tubular joint body portion having an internal flow path (P) for allowing a fluid to flow therein; and two or more welding end portions, which are respectively provided at two or more opening portions of the internal flow path (P), and which are configured to be welded while being butted against end portions of other resin tube members or end portions of other resin pipe joints. The flow path cross-sectional area of the internal flow path (P) in the joint body portion is constant, at least in portions that are adjacent to the welding end portions and whose outer diameters are straight.

A pipe fitting includes an entry hub, an exit hub, and a cleanout hub. The cleanout hub is coaxially aligned with the exit hub and angularly offset from the entry hub. The pipe fitting also includes a main body that extends between the cleanout hub and the exit hub. The main body defines a main body length that is at least three times greater than the exit hub outer diameter.

A sprinkler adapter includes a first pipe receiver, a second pipe receiver, a channel, a first sprinkler port, and a second sprinkler port. The first pipe receiver couples with a first pipe. The second pipe receiver couples with a second pipe. The channel extends between the first pipe receiver and the second pipe receiver along a pipe axis. The first sprinkler port is fluidly coupled with the channel, couples with a first sprinkler, and defines a first port axis spaced from the pipe axis. The second sprinkler port is fluidly coupled with the channel, couples with a second sprinkler, and defines a second port axis spaced from the first port axis and the pipe axis.

A multi-functional fitting for piping, tubing or other conduit comprises: a body defining a channel between three ports; a test plug at one port; and a secondary valve at a second port. The test plug comprises a self-closing valve. The test plug is configured to receive a tip of an instrument such as a measuring probe. The secondary valve comprises a different valve configuration and is selectively operable between an open and a closed position. Coupling mechanisms are provided at the second a third port. In an example, the coupling mechanisms are different types. The fitting may be T-shaped, Y shaped, shaped or the like. A method is provided to measure a gas property or maintain a sensor processing unit using the multi-functional fitting.

A motor vehicle fluid line for conducting at least one fluid medium, in particular for conducting urea solutions for SCR catalytic converter systems, at least one fluid-carrying pipe and at least one fluid-carrying connector that is connected to the pipe being provided. The pipe comprises a fluid-carrying outer line and a fluid-carrying inner line that is received in the outer line over at least part of its length L. The connector comprises a first connecting branch that is in fluid communication with the outer line, and comprises a second connecting branch that is in fluid communication with the inner line.

A quick-fitting pipe fitting assembly for coupling with at least one pipe element includes a pipe fitting body, at least one coupling unit, and at least one gasket. Each coupling unit includes a fixed coupling element integrally extended from the pipe fitting body and a movable coupling element, the gasket disposed at the coupling unit, the connecting elements movably connect the fixed coupling element with the movable coupling element, wherein the at least one coupling unit is adapted for being preassembled with the at least one pipe element and can be fastened by at least one fastening element that is capable of being operated to fasten the movable coupling element with the fixed coupling element.
