Frequently Asked Questions (FAQ)
What are FORMUFIT PVC products?
FORMUFIT PVC products are fittings and pipe, specifically designed to build structures and projects. FORMUFIT fittings and accessories allow inventors, designers, makers, and DIY enthusiasts to create innovative structural applications from simple, inexpensive PVC pipe available in the plumbing department of almost any hardware store.
What is the difference between all of the different sizes of pipe and fittings?
PVC pipe comes in a variety of sizes. FORMUFIT PVC products are designed so that individuals can produce any application or structure needed using almost any size pipe that their project requires. For example, some pipe is more robust, more rigid, and ideal for designs that bear weight, while some tubes are more agile and flexible, perfect for creating curved surfaces and smaller applications. Essentially, the pipe is chosen based on the design or need.
Check out our easy-to-use PVC Size Guide to determine your project's most suitable PVC pipe size.
What is the best way to determine what size or fitting I need for my project?
Drawing out your design and planning first are great methods to determine your need. Another approach is to download our PVC fitting and pipe components for SketchUp. You can build and even test your design using SketchUp before you place your order.
Additionally, you can download and print our PVC Pipe Size Guide to see actual pipe sizes and attributes to see which size PVC pipe is for you.
Do I need to use FORMUFIT pipe with FORMUFIT fittings?
Nope. You don't have to use our pipe. You can use our Furniture Grade PVC fittings with standard plumbing-grade PVC pipe from your local hardware store or home center; however, plumbing-grade PVC does have drawbacks compared to FORMUFIT Furniture Grade PVC pipe. Limitations such as short life in the sun, yellowing, manufacturer's ink and stampings, brittleness, and a matte or dirty appearance make plumbing pipe a less-than-stellar solution. However, we offer some ideas on 'beautifying' plumbing-grade PVC pipe in our PVC How-To Guides section, specifically our PVC Pipe Cleaning Guide.
Can I use CPVC or CTS pipe with your fittings?
No. Our fittings will only work with Schedule 40 PVC pipe available in the plumbing section of your hardware store or available in our store. CPVC and CTS use a different measurement system incompatible with Schedule 40 PVC fittings. You can identify CPVC and CTS pipe by their tan or light-brown color, whereas standard PVC is white.
You can see more information on these types of pipes on our PVC vs. CPVC Compatibility page.
Can I use Thinwall PVC pipe with your PVC fittings?
Yes, but only for our external fittings. While the outside diameter will match, Thinwall PVC does not have the correct inside diameter to accommodate our internal fittings and accessories. FORMUFIT internal fittings and accessories will only fit inside Schedule 40 PVC Pipe.
How do I know which size of pipe will work with the right size fitting?
What is the difference between FORMUFIT PVC fittings and plumbing fittings?
When you put them side-by-side, the difference is quite clear. Despite the appearance, our fittings have the following benefits over plumbing-grade PVC fittings:
- Glossy, clean white, black or bright-color, UV-resistant exterior.
- No stampings, raised lettering, embossments, or barcodes.
- All FORMUFIT products are a completely solid color.
- Completely non-toxic and contain no heavy metals, harmful dioxins, phthalates, or other dangerous chemicals.
- Tapered, clean edges for increased appearance.
- Multiple configurations (3-Way, 4-Way, 5-Way) not found in plumbing-grade fittings.
Can I use your fittings or pipe for plumbing installation or repair?
FORMUFIT PVC fittings and pipes are not National Sanitary Foundation (NSF) rated for plumbing applications. Our fittings are specifically designed for structural purposes and are not designed for plumbing use. While they will work in plumbing applications, they may fail inspection, as they are unmarked. FORMUFIT products CAN be used for irrigation, aquaponics, and aquarium applications since there is usually no inspection required.
What is the best way to contact FORMUFIT if I have questions about a product?

2. If you created an account, you can log into your account and click on the order number, then click the 'Edit' button to modify your order.
Do you accept returns?
We accept returns for any fittings and accessories. We do not accept returns for PVC pipe due to the custom cut-to-order nature of our pipe. For more information on returns, please see our Product Returns Policy page.
