Plugs and end caps
The main plug styles are:
- Female: end caps with a "socket" opening, into which you can glue either a pipe or a male fitting
- Male: plugs with "spigot" fitting, which fit inside a female fitting of the same size.
- Barb: plugs that are designed to slide directly inside a pipe.
- Manifold: plugs that are designed to fit into or over barb fittings on other parts, particularly manifolds.
