You do not want MIP, it is for compressed fittings. Get the part i mentioned, and you will be happy. 1/2" Pipe to 1/2" Female NPT.

As far as explaining MIP, do not worry, as far as explaining NPT (National Pipe Thread), i'll give it a try.

NPT is sometimes confused and intermixed with copper and plastic pipe sizing(unthreaded pipe pieces).

Pipe sizing measurement describes the smallest ID dimension for a particular family of sizes. IE: 1/2" pipe parts will all work with eachother, and all their smalles ID dimensions will be approx. 1/2". The pipe itself is closest to this standard. The connectors, ie: elbows, converters, t's all will accept the 1/2" pipe. The 1/2" pipe will slip into the connectors.

NPT is used to describe the thread sizes of parts that sometimes are used with pipe and sometimes with barbs. For instance we generally see waterblocks with 1/4" MALE NPT X 1/2" Barb. The barb is measured by what hose will fit over it, so it is actually larger than 1/2" in diameter. Depending on the manufacturer the id of the NPT side will be anywhere from 1/4 to 2/8".

Hope it helps,
