📚 Meaning of FIP in Plumbing (Full Explanation)
🔧 What Does FIP Stand For?
FIP = Female Iron Pipe
It refers to a fitting that has internal threads. These threads allow it to connect with a male-threaded pipe, commonly known as MIP (Male Iron Pipe).

- Water supply lines 🚰
- Gas line connections 🔥
- Faucets and shower installations 🚿
- Valves and adapters
They are designed for durability and secure sealing under pressure.
🔗 How FIP Works
A FIP fitting screws onto a male-threaded pipe (MIP).
Example:
- A water valve with FIP threads will screw onto a pipe with MIP threads.
- The connection is sealed using thread tape (Teflon tape) or pipe joint compound.
👉 This prevents leaks and ensures strong connection.
