I still remember the first time I tried to fix a leaky pipe under my kitchen sink. I went to the hardware store and confidently asked for “that L-shaped plastic thing.” The guy behind the counter just stared at me. Apparently, in the world of pvc pipe fittings, there’s a specific name for everything!
If you’re planning a DIY plumbing project or just want to make sure your plumber isn’t overcharging you for “fancy parts,” you need to know your pvc pipe fittings names. It’s not just about connecting two pipes; it’s about controlling flow, pressure, and direction. In this guide, I’m breaking down the most common plumbing fittings names and pictures so you can shop like a pro.
What Are PVC Pipe Fittings?
Basically, pvc pipe fittings are the joints and connectors that hold your plumbing system together. PVC stands for Polyvinyl Chloride, which is a fancy way of saying a very durable, rust-proof plastic.
These fittings are the heroes of your home. Without them, your pipes would just be straight lines going nowhere. They are used everywhere, from the pipes bringing fresh water to your shower to the ones taking waste out of your house. They’re popular because they are cheap, light, and honestly, they last forever if you install them right.

Types of PVC Pipe Fittings Names & Images
Let’s look at these pipe fittings names and images in a bit more detail so you don’t end up with the wrong part.
1. PVC Elbow Fitting
The elbow is probably the most used item in any pvc pipe fittings names and images gallery. It allows you to turn a corner.
Common Uses: Navigating around walls, corners, or floor joists.
Types: Available in 90-degree (sharp turn) and 45-degree (gentle turn).
2. PVC Tee Fitting
Looking like the letter “T,” this fitting has three ends.
Common Uses: Branching off a water line to supply a new sink or appliance.
Types: Standard Tee, Diverter Tee (used in heating), and Sanitary Tee (for drainage).
3. PVC Coupling
This is the simplest fitting. It’s just a small sleeve that connects two straight pipes.
Common Uses: Extending a pipe run or repairing a broken section.
Types: Standard (with a middle ridge) and Slip (no ridge, slides freely for repairs).
4. PVC Reducer
When plumbing systems involve pipes of varying diameters, a PVC joint known as a reducer ensures a snug fit between them. This fitting is essential for transitioning from larger to smaller pipes, helping to regulate water pressure effectively. It’s commonly used in home plumbing networks, such as in kitchen sinks or garden irrigation setups, allowing for a smooth flow of water between pipes of different sizes.
Common Uses: Connecting pipes with different diameters.
5. PVC Cross Fitting
The cross-fitting is a versatile piece in the PVC items list, featuring four pipe connection points that allow water to branch off in multiple directions. This unique design is ideal for systems requiring several outflows, such as in irrigation fields or complex residential layouts where water is distributed to various rooms or outdoor areas of the property.
Common Uses: Plumbing systems that require distribution in multiple directions.
6. PVC Cap
Used primarily to seal the ends of pipes, PVC caps are a common component in the types of PVC fittings. They are often utilized during home plumbing repairs or when pipe extensions are not yet needed. PVC caps prevent debris or pests from entering the system while maintaining water flow control. These fittings are simple yet essential for closing off unused pipe ends during renovation projects, offering a temporary or permanent seal.
Common Uses: Temporary or permanent pipe closure.
7. PVC Union
Unlike a coupling, a union can be unscrewed.
Common Uses: Near pumps or filters that need to be replaced or cleaned often.
Types: Standard and Dielectric (to prevent corrosion between different metals).
8. PVC Plug
A PVC plug, much like other PVC joints, is used to seal off the ends of pipes, but instead of being slipped on, it is typically screwed in for a more secure fit. Commonly utilized in underground plumbing systems such as sewer lines or irrigation setups, these plugs ensure that the pipes remain tightly closed until further extensions or maintenance are needed, effectively protecting the system from external elements like dirt or debris.
Common Uses: Sealing pipe ends for maintenance or repair.
9. PVC Wye Fitting
Shaped like a “Y,” this fitting, known as the Wye fitting, directs water at a 45-degree angle, making it ideal for drainage systems. It is commonly found in bathroom PVC pipe fittings to efficiently redirect wastewater from various branches into a main sewer line, ensuring proper water disposal without blockages. This design is essential in both residential and commercial buildings, facilitating smooth drainage while minimizing the risk of clogs in the plumbing system.
Common Uses: Connect pipes at a 45-degree angle for smooth directional flow.
10. PVC Flange
A PVC flange provides a stable and secure connection between pipes and fixtures, commonly found in toilets or drainage systems. As an essential component in PVC plumbing items, it creates a watertight seal, preventing leaks and ensuring the secure attachment of piping to other plumbing materials, such as bathroom fittings or heavy-duty drains. This fitting is crucial for maintaining the integrity of plumbing systems, particularly in high-use areas like bathrooms, where reliable connections are necessary to avoid costly repairs.
Common Uses: Easy access for assembly, disassembly, and maintenance in plumbing systems.
11. PVC Bushing
PVC bushings are essential PVC fittings that help reduce pipe sizes for specialized connections, making it easier to link larger pipes to smaller ones. These fittings are commonly seen in industrial settings or during property construction, where varying pipe diameters are necessary to control water flow across different building sections. Their adaptability and functionality make them a crucial part of the PVC fittings names list, ensuring efficient water management in various applications.
Common Uses: Reducing the pipe size while maintaining a secure, leak-proof connection.
12. PVC Trap
Installed beneath sinks or basins, PVC traps are vital PVC pipe fittings that prevent harmful sewer gases from entering the home while trapping debris that could otherwise clog the plumbing system. These fittings play a critical role in household maintenance, offering both health benefits and plumbing protection. Their importance in ensuring a safe and efficient plumbing system makes them essential items in the list of PVC pipe fittings names, particularly in modern homes.
Common Uses: Prevent sewer gases from entering buildings by trapping water in the bend of the pipe.
13. PVC Saddle Tee
The saddle tee fitting is a versatile type of PVC pipe fitting designed to add a branch line to an existing pipe without the need for complicated cutting or restructuring. It’s frequently used in irrigation systems or when installing new plumbing lines to a home’s main water supply, making it an essential choice for various home and garden projects. This fitting allows for easy connections while maintaining the integrity of the existing plumbing system.
Common Uses: Adding connections without cutting into the pipe.
Applications of PVC Pipe Fittings
Where do these actually go? Most people only think of the bathroom, but plumbing fittings names pop up everywhere:
Residential Plumbing: Your sinks, toilets, and showers.
Drainage Systems: DWV (Drain-Waste-Vent) systems that use gravity to move waste.
Agricultural Irrigation: Sprinklers and farm water lines.
Electrical Conduit: Protecting wires from moisture and soil.
Advantages of Using PVC Pipes
Why not use metal? Well, pvc pipe fittings have some huge wins:
Corrosion Resistant: They won’t rust like old iron pipes.
Lightweight: You don’t need to be a bodybuilder to carry a 10-foot pipe.
Cost-Effective: By far the cheapest way to build a plumbing system.
Easy Installation: If you can use glue, you can (mostly) do PVC plumbing.

Tips for Choosing the Right PVC Pipe Fittings
Check the Schedule: Schedule 40 is standard for homes; Schedule 80 is thicker and used for high pressure.
Match the Size: A 1-inch pipe needs a 1-inch fitting. Seems obvious, but check the labels!
Pressure Rating: Make sure the fitting can handle the PSI of your water pump.
Use the Right Primer/Glue: PVC won’t stay together without the purple primer and solvent cement.
Look at the “Gender”: Remember, male threads go into female threads.
Final Thoughts
Understanding pvc pipe fittings names might seem like a lot of “geek speak,” but it saves you time and money. Whether you are browsing pipe fittings names and images for a school project or fixing a burst pipe in the middle of the night, knowing the difference between a “Coupling” and a “Union” is the first step to success.
Always remember to double-check your measurements before applying that glue, because once PVC is set, it’s permanent!
PVC Pipe Fittings Names and Images FAQs:
1. What are the most common pvc pipe fittings names I should know?
If you are starting a project, the essential pvc pipe fittings name list includes the Elbow (for turns), Coupling (to join pipes), Tee (for branches), and Reducer (to change pipe size). For systems that need occasional maintenance, a Union is also a must-have.
2. Where can I find a guide for plumbing fittings names and pictures?
Most hardware stores and online DIY blogs (like ours!) provide a full gallery of plumbing fittings names and pictures. Seeing the image helps you distinguish between similar parts, like a Cap (which goes over a pipe) and a Plug (which goes inside a fitting).
3. What is the difference between an Elbow and a Sweep Elbow?
While both are standard plumbing fittings names, a standard Elbow has a sharp 90-degree turn. A Sweep Elbow has a gradual curve, which is one of the best pvc pipe fittings for drainage because it prevents clogs and reduces friction.
4. Why do I need to see pvc pipe fittings names and images before buying?
Many fittings look similar but serve different purposes. For example, looking at pvc pipe fittings names and images helps you realize that a "Sanitary Tee" has a specific curve for waste flow, whereas a "Pressure Tee" is for high-pressure water supply.
5. Can I use different pipe fittings names and images for hot water?
No. Standard white pvc pipe fittings are only for cold water. If you see pipe fittings names and images for yellowish pipes, those are CPVC, which can handle heat. Using regular PVC for hot water will cause the joints to melt and leak!
6. How do I choose between a Coupling and a Union?
Both appear on every pvc pipe fittings name list, but a Coupling is a permanent, glued joint. A Union has a screw-on nut in the middle, allowing you to take the pipes apart later without cutting them, perfect for pool pumps or water heaters.
