FIP stands for Female Iron Pipe. It's a type of threaded pipe fitting commonly used in plumbing systems. FIP fittings have internal threads that allow them to connect to pipes with external (male) threads. These fittings are typically made of materials like galvanized steel, brass, or plastic and are used to create secure, leak-proof connections in plumbing systems.

• Application: FIP fittings are used in various plumbing applications, including water supply lines, gas lines, and drainage systems. They are known for their durability and strength, making them suitable for high-pressure systems.
• Compatibility: FIP fittings are designed to connect with Male Iron Pipe (MIP) fittings, which have external threads. When combined, FIP and MIP fittings create a tight, threaded seal that prevents leaks.
• Material: While traditionally made of iron or steel, FIP fittings can also be found in brass and plastic, each offering different advantages depending on the plumbing application.

1. MIP (Male Iron Pipe):

• Definition: MIP stands for Male Iron Pipe, referring to fittings with external threads that connect with FIP fittings.
• Use: These fittings are used in the same applications as FIP fittings and are essential for creating threaded connections in plumbing systems.

1. PTFE (Polytetrafluoroethylene) Tape:

• Definition: Also known as Teflon tape, PTFE tape is a thin, white tape used to seal threaded pipe joints.
• Use: Wrapping PTFE tape around the threads of pipe fittings helps prevent leaks by creating a watertight seal.

1. PVC (Polyvinyl Chloride):

• Definition: PVC is a type of plastic commonly used for plumbing pipes and fittings.
• Use: PVC pipes are lightweight, durable, and resistant to corrosion, making them ideal for water supply lines and drainage systems.

1. Sweating:

• Definition: In plumbing, sweating refers to the process of soldering copper pipes and fittings.
• Use: This technique involves heating the pipes and applying solder to create a strong, leak-proof joint.

1. PEX (Cross-linked Polyethylene):

• Definition: PEX is a flexible plastic tubing used for water supply lines.
• Use: PEX is easy to install, resistant to freezing, and compatible with various types of fittings, making it a popular choice for modern plumbing systems.
