Frequently Asked Questions (FAQ)
FORMUFIT PVC products are structural PVC elements that work with most standard off-the-shelf PVC pipe. PVC fittings are more familiar to most people in plumbing applications, however FORMUFIT products are specifically designed to be used to build structures and projects. FORMUFIT fittings and accessories allow inventors, designers, makers and the DIY enthusiast to create innovative structural applications from simple, inexpensive PVC pipe available in the plumbing departments of most home centers and hardware stores.
Anything you can possibly imagine. You can create anything from pet equipment to artwork, from PVC furniture to carts and holiday displays. Think of FORMUFIT products as the pieces of a giant Tinkertoy set, for kids and adults alike. Both consumers and businesses benefit from our products. You can get some ideas in our Free PVC Plans and Projects section or view our PVC Project Ideas on Instagram.
PVC pipe comes in a variety of sizes. FORMUFIT PVC products are designed so that individuals can produce any application or structure needed using whatever pipe that their needs require. Some pipe is stronger and more rigid and ideal for structures that bear weight (1 in. Size PVC and up), while some pipe is more agile and flexible, which is ideal for creating curved surfaces and smaller applications (3/4 in. Size PVC and below). In essence, the pipe actually is chosen based on the design and need. Check out our easy to use PVC Size Guide to determine the best PVC pipe size for you.
Drawing out your design and planning first are the great methods to determine your need. Another method is to download our PVC fitting and pipe components for SketchUp. Using these programs (SketchUp is free to use), you can build, and even test out your design, 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.
Nope. 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 PVC pipe, such as limited life in sunlight, yellowing, manufacturers ink and stampings, brittleness and matte appearance. We do offer a few ideas on how to 'beautify' plumbing-grade PVC pipe in our PVC How-To Guides section, specifically our Cleaning PVC Pipe guide.
No. Our fittings will only work with standard PVC pipe available in the plumbing section of your hardware store. CPVC and CTS use a different system of measurement that is not compatible with standard PVC sizes. You can identify CPVC and CTS pipe by its tan or light-brown color, whereas standard PVC is white in color. See more information here.
Yes, but only for our external fittings. While the outside diameter will match, the inside diameter of Thinwall PVC does not have the correct diameter to accommodate our internal fittings and accessories. Our internal fittings and accessories will only fit inside Schedule 40 PVC Pipe.
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 UV-resistant exterior.
- No stampings, raised lettering or barcodes, all our products are a completely solid color.
- Completely non-toxic and contain no heavy metals (such as lead), noxious dioxins, phalates or other dangerous plasticizers.
- Tapered, clean edges for increased appearance.
- Interior detent consistent across all of our fittings. Multiple configurations (3-Way, 4-Way, 5-Way) not found in plumbing-grade fittings.
- Special accessories made specifically for PVC structure applications.
Acetone or a sanding block is the best solution for removing factory ink and barcodes from PVC pipe. Refer to our Cleaning PVC Pipe instructions in our PVC How-To Guides section. Also, be sure to view our PVC PipeSleeves as an alternative to cleaning PVC pipe markings.
FORMUFIT PVC fittings and pipe are not National Sanitary Foundation (NSF) Rated for plumbing applications. Our fittings are specifically designed for structural purposes and other applications only and are not designed for plumbing use. While they will work (and in most cases, outperform) for plumbing use, 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.
No. Absolutely not. Our flexible shipping structure allows you to order only the fittings you need at a low cost. We are the only PVC provider online to offer the use of the USPS First Class mail to allow small inexpensive shipments (under 13 oz.) to be sent for under $4 anywhere in the US.
