Pipe Fittings
Pipe fittings are parts used in piping systems to join pipes together, change direction, control flow, and provide sealing. They are essential for constructing robust and efficient piping networks in residential, commercial, and industrial applications. Pipe fittings are specialized connectors that enable us to:
Change Direction
Elbows, bends, and tees allow us to navigate corners, obstacles, and change the flow path within the piping system.
01
Reduce or Increase Diameter
Reducers and expanders adjust the pipe diameter to accommodate different sections or connect pipes of varying sizes.
02
Join Pipes
Couplings and unions create a permanent or temporary connection between two pipe ends.
03
Block Flow
Caps and plugs seal off the end of a pipe, preventing unwanted flow or leaks.
04
Control Flow
Valves regulate the flow of fluids, allowing for opening, closing, or adjusting the flow rate.
05
Elbows: Used to change the angle or direction of the pipe run. Most commonly in 90 degrees and 45 degree turns. The sweep of the fitting describes how fast a transition or change in direction is made.
Street Elbows: One end of the pipe fitting has male threads and the other end has female threads. These are common in galvanized steel and copper pipe. They are convenient because they do away with the need for a nipple and work well in tight quarters.
Tee Fittings: Shaped like the letter T. Allows for branch lines.
Couplings: Used to join two straight pieces of pipe of the same diameter.
Reducers: Used to join pipes of different diameters. Makes a gradual change in diameter.
Bushings: Used to make the diameter of a pipe fitting smaller. They are different from reducers because they make an abrupt change in diameter and take little space.
Unions: Used to join pieces of pipe where pipes cannot be turned or when a piece of equipment may have to be removed for maintenance or replacement.
Adaptor Fittings: Used to change the end of a non-threaded pipe to male or female threads as needed. Most commonly used in copper and plastic plumbing jobs.
Caps: Used to close the end of a dead-end pipe.
Plugs: Used to close an ending on a pipe fitting normally used for inspection or cleanout.
Nipples: Short lengths of pipe threaded at both ends.
Wyes: Used primarily to gain inside access to DWV (drain-waste-vent) systems.
Valves: Devices that control the flow of liquid or gas through or from a pipe. (Compression valves, ball valves, sleeve-cartridge valves, ceramic disc valves, etc)
PVC Fittings: Come in a wide variety of configurations and may be glued (S) or threaded (T)
Copper Tubing Fittings: Use compression fittings. Common fittings are couplings, ells, and tees.
Pipe fittings are made from various materials, each offering unique properties suited to different applications:
1. Metal
●Steel: Strong and durable, used in high-pressure and high-temperature applications.
●Stainless Steel: Corrosion-resistant, ideal for chemical and food industries.
●Copper: Excellent for plumbing due to its corrosion resistance and ease of use.
●Brass: Used for its corrosion resistance and durability in plumbing and HVAC systems.
2. Plastic
●PVC (Polyvinyl Chloride): Lightweight, cost-effective, and corrosion-resistant, used in drainage and low-pressure applications.
●CPVC (Chlorinated Polyvinyl Chloride): Similar to PVC but with higher temperature resistance.
●HDPE (High-Density Polyethylene): Flexible and durable, used in water supply and gas distribution.
●PEX (Cross-linked Polyethylene): Flexible and easy to install, commonly used in water supply systems.
3. Other Materials
●Concrete: Used in large-scale water and sewage systems for its strength.
●Clay: Traditionally used in sewer systems.
●Fiberglass: Lightweight and corrosion-resistant, used in chemical and industrial applications.
How to Choose Pipe Fittings
Materials
Depending on the pipes you're using and the temperatures required, different fittings will be more compatible with the job.
End Connections
Before buying a fitting, you must know the end connection type the fitting needs to suit.
Type of Pipe Fitting
Is it threaded or slip? Male or female? Know the type you're looking to fit prior to purchase to ensure they are truly compatible.
Size
Size also must be taken into account to make sure the pipe and fittings work together.
Pressure Rating
To find a proper fitting that suits the internal pressure, know the pressure rating before starting your search.
Standards and Codes
Depending on what you're working with, there are different codes and standards for fittings that you'll need to know to fit your design.
