A pipe fitting or adapter creates a union between two straight sections of pipe to extend the length or change flow directions within a piping system. It can also be used to connect two different sizes of pipe or components depending on the requirements of the system design.
Lennox line sets may be used up to 50 feet linear length (not including equivalent length of fittings). Lines over 50 feet up to 150 feet linear should be sized in accordance with section V. Applications with less than 50 linear feet of refrigerant line may use RFC metering devices on approved matchups as listed in Lennox’ Engineering Handbook.

The equivalent length values can be used with reasonable accuracy for copper or brass fittings and bends although the resistance per foot of copper or brass pipe is less than that of steel. For copper or brass valves, however, the equivalent length of pipe should be taken as 45 percent longer than the values in the table, which are for steel pipe.
For example, copper pipe that measures 5/8 inch OD, is called 1/2-inch pipe. The ID varies because wall thickness varies. Type K has the thickest wall, followed by Type L, Type M and DWV. ... To determine the length of pipe needed to connect two fittings, take two dimensions into account: The fitting socket depth and the laying length. The ...
Thus the set of fittings in given 6" line are equivalent to 60.36 m of that line. Along with the original 200 m of straight pipe, the total equivalent length of the given 6" line becomes 260.36 m. This length can be used to quickly calculate variation of pressure drop for minor variations in the flowrate, ...

If your home has copper water piping and those pipes were installed before 1986, your copper pipe/fittings were generally joined or soldered together with "50/50" solder. 50/50 solder was comprised of 50% lead and 50% tin and had been used by the majority of plumbers to join copper pipe and fittings for many decades.
