1/2-inch pipe fittings
A reminder of the different types of plumbing fitting:
- F: a female or "socket" opening, into which you can glue either a pipe or a male fitting.
- M: a male, or "spigot" fitting, with the same external diameter as the corresponding pipe, which will slide inside a female fitting of the same type.
- M+: a "barb" fitting which is designed to slide inside a pipe. This type of fitting, which can be smooth or ribbed, is very useful if you cannot glue a pipe into a female fitting, due to lack of space, for example, and works best with small pipes (especially 1 inch and less) from the same manufacturer as the fitting.
