These questions often have to do with pipe fittings sizes and dimensions, which makes sense because those topics can be confusing! Other questions are about the fittings themselves and what they are meant for.
Compatibility and general pipe fitting knowledge can be overwhelming to someone who is new to the world of PVC! If you are trying to expand your PVC knowledge, you can use this blog post as a pipe fitting study guide!
This pipe fittings guide will outline all the major types of PVC fittings as well as how and why to use them. This is a long post, so you can use the "Contents" section to navigate it!
As mentioned in a previous blog post about PVC pipe outer diameter, PVC pipe and fittings use a nominal system for standard sizing. This is so all parts with the same size in their name will be compatible with each other.
All 1" fittings will fit on 1" pipe, for example. That seems pretty straightforward, right? Well here's the confusing part: the outer diameter OD of PVC pipe is greater than the size in its name.
The most important thing when working with PVC pipe and fittings is the nominal size. A 1" fitting will fit on a 1" pipe, regardless of whether either one is schedule 40 or So, while a 1" socket fitting has an opening wider than 1" across, it will fit on a 1" pipe because the OD of that pipe is also greater than 1".
The nominal size, in this case, is not as important as the OD of the pipe you are using. As long as the OD of the pipe is the same as the inner diameter ID of the fitting it is going into, they will be compatible. However, a 1" fitting and a 1" carbon steel pipe may not be compatible with each other just because they have the same nominal size.
Be sure to do your research before spending money on parts that may not be compatible with each other! Click here for more information on PVC outer diameter. Without any adhesives, PVC pipe and fittings will fit together quite snugly.
They will not, however, be watertight. If you are going to have any fluids passing through your pipe, you will want to ensure that there will be no leaks. There are several different ways to do this, and the method you choose will depend on what you are connecting.
PVC pipe itself does not usually have threaded ends. This is just one reason that most PVC fittings have slip ends. When putting pipe into a slip fitting, the connection may seem tight, but to transport any liquid media, it will need to be sealed.
PVC cement seals pipe through a chemical reaction that bonds the plastic of one part to another. The primer softens the inside of the fitting, preparing it to bond, while the cement keeps the two pieces stuck together tight.
Threaded fittings need to be sealed differently. The main reason people use threaded parts is so that they can be taken apart if necessary. PVC cement bonds pipe together, so if it is used on threaded joints, it will make a seal, but the threads will become useless. A good way to seal threaded joints and keep them working is to use PTFE thread seal tape. UPVC Fittings. While operating from India and UAE we take great pride in our scientifically backed products and the efforts that we make everyday to improve people's lives.
We employ the latest world class machines. Our computerised quality control lab, logistics division, all speak volumes of our penchant to keep in tune with the times. Flanges have excellent chemical resistance to withstand a variety of salt solutions, acids, and other harsh substances.
They are also known as Victaulic flanges. These fittings are NSF certified for use in corrosive waste gravity-flow systems. Made of CPVC, they have better chemical resistance than ABS plastic gravity-flow fittings and can stand up to highly-corrosive acids and other harsh substances. Use this pipe in gravity-flow applications that involve highly-corrosive chemicals— it is NSF certified for use in corrosive waste systems.
These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent DWV applications. Also known as Schedule 40 flanges, they are the industry standard for gravity-flow drain, waste, and vent DWV applications. With thinner walls than Schedule 40 fittings, these are lighter in weight and have more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines.
They are also known as SDR 35 fittings. These adapters connect PVC waste pipe to cast iron pipe without adding bulk. Instead of securing pipes together from the outside like clamp-on couplings, these flexible adapters fit into cast iron pipe to create a tight compression seal. Connect two pipes that are up to feet apart— cut the connector to the length you need and attach a clamp to each end. These connectors are for use in low-pressure air and vacuum conveying systems, as well as in gravity-flow systems.
Also known as no-hub couplings, these have a one-piece sleeve with a stop in the center, so you know your pipe is always aligned correctly. A turn of the T-handle will tighten and loosen these connectors, so you can quickly disassemble and reassemble your lines without tools. Use in medium-pressure applications up to psi. Use in high-pressure applications up to psi.
These joints are designed for vertical use in drain, waste, and vent systems. Choose these metal fittings when you need better durability than our plastic push-to-connect fittings. Minimize leaks in your line— these fittings have a single barb that creates a smooth clamping surface for extra-tight connections. The nickel plating on these fittings provides better corrosion resistance than unplated brass fittings. Made of stainless steel, these fittings have better corrosion resistance than brass fittings.
Tube supports slip inside tubing to prevent the walls from collapsing. Made of brass, these couplings are more durable than plastic couplings.
Use these nuts with brass compression fittings to create a seal on plastic tubing. Made of stainless steel, these fittings are more durable than plastic barbed tube fittings for food and beverage. A smooth interior reduces friction and prevents product buildup, ensuring an unrestricted flow. Made of FDA listed materials, these fittings have a single barb that creates a smooth clamping surface for extra-tight connections.
Fittings have a barb that grips onto tubing. Use in applications up to psi. Clear All.
