Glossary of terms

If you visit a home improvment center you will find an overwhelming array of fittings and connectors for hooking up water lines, gas lines, sewer lines, water heaters and others. The vocabulary is strange and the variations subtile, but very significant.

Glossary of terms:

FIP - Female Iron Pipe. Used to describe a fitting threaded to go onto old style galvanized iron pipe.

Flare - Flare fittings are made of brass and used for gas line connections. If your water heater gas supply line is made of copper there is a good chance it is connect with a flare fitting. You need a flaring tool and the right kind of copper line (plus some skill) to make it work.

Compression - Compression fittings are common on water supply lines. The most common flexible line would be a toilet supply line with a 3/8" compression fitting on one end and the toilet tank size on the other.
