A gladhand connector or gladhand coupler is an interlocking hose coupling fitted to hoses supplying pressurized air from a tractor unit to air brakes on a semi-trailer, [1] or from a locomotive to railway air brakes on railroad cars. [2] Gladhand connectors resemble a pair of "hands shaking" when interlocked, hence the name. [1]

The fitting is known as a reducing coupling, reducer, or adapter if their sizes differ. There are two types of collars: "regular" and "slip". A regular coupling has a small ridge or stops internally to prevent the over-insertion of a pipe and, thus, under-insertion of the other pipe segment (which would result in an unreliable connection).
Also, larger aluminum stranded building wire made with AA-8000 series alloy of aluminum is used for electrical services (e.g. service entrance conductors from the utility connection to the service breaker panel) and for larger branch circuits such as for sub-panels, ranges, clothes dryers and air-conditioning units.

Allura Red AC is a popular dye used worldwide. Annual production in 1980 was greater than 2.3 million kilograms. [5] It was introduced as a replacement for amaranth in the United States. [6] The European Union approved Allura Red AC as a food colorant in 1994, but EU countries' local laws banning food colorants were preserved. [7]
Pipe coupling (copper sweat) In piping and plumbing , a coupling (or coupler ) is a very short length of pipe or tube , with a socket at one or both ends that allows two pipes or tubes to be joined, welded ( steel ), brazed or soldered ( copper , brass etc.) together.
For example, 1.107 in (28.1 mm) diameter ACCC "Drake" conductor at 75 °C has an AC resistance of 106 mΩ/mile, [7] while equivalent ACSR conductor has an AC resistance of 139 mΩ/mile, [8] 31% higher. Sag Comparison Test Data: temperature vs. sag of various conductor types on a 215' test span.
