What Does FIP Mean for a Plumber?

If you have ever tried to attempt a DIY pipe replacement project, you would have probably heard about “FIP”, one of the most common acronyms in the plumbing industry. Knowing what it means can help you identify the issue and fix it. If you ever feel unsure about your home’s overall comfort systems, you can always schedule a home system inspection to make sure everything is working safely.

FIP vs MIP

Next thing to note is MIP, “male iron pipes”, these pipes have exterior threading where internal threads of a FIP get attached to. Additionally, similar to FIP, MIPs are sometimes called MPTs when the material isn’t iron. 

The exterior thread of an MIP fits into the interior thread of an FIP. A lot of licensed plumbers use plumbers’ tape to secure MIP threads before attaching two pipes. This technique fills in any gaps to prevent leaks. 

These pipe fittings are common for connecting gas lines to heaters, dryers, and washing machines. It’s extremely important to get the sizing right so as to prevent gas leaks and other hazards.
