The component parts of a drain tube as I make it. From left to right are the following:

• Tube cap
• Tube (1 1/4 inch)
• Coupling (1 1/4 inch)
• Bushing (1 1/4 X 1/2) (This one is threaded for a 1/2" spigot; I prefer the one that's threaded
• for 3/4" spigot)
• Spigot (1/2 ", otherwise known as a hose bib)
• Pipe Clamp To fit the 1 1/4 inch pipe

Below is a picture of the components assembled.
