Plastic Fittings: What Are Pipe Inserts and How Do They Work?
Pipework needs the right support to stay secure and work well. Small parts can make a big difference during installation. One useful example is a pipe insert. These simple components sit inside plastic pipe ends and help support the pipe when a fitting is connected.
For many plumbing and heating jobs, plastic fittings provide a practical way to connect, support, and protect pipe systems. They are available in different shapes and sizes, so you can select products that suit your project.
In this guide, we will explain what pipe inserts are, how they work, how they are made, and why they can be useful. We will also look at 15mm and 22mm pipe stiffener inserts and explain what to check before you shop.
What Are Plastic Fittings?
Plastic fittings are components used with plastic pipe systems. They can include connectors, inserts, elbows, tees, adaptors, and other parts that help create a complete pipe installation.
A pipe insert has a more specific job. It fits inside the end of a plastic pipe before the pipe connects to another component. The insert supports the inside of the pipe and helps the connection keep its shape.
You can explore the plastic fittings category to find different plastic products for plumbing and other applications.
What Are Pipe Inserts?
Pipe inserts are small support components designed to sit inside plastic pipes. They are also known as pipe stiffener inserts.
When a fitting is attached to a plastic pipe, the pipe wall can need extra internal support. An insert helps provide that support. As a result, the pipe can maintain its shape around the connection.
This makes pipe inserts useful in many plumbing applications. They are particularly helpful when a compression fitting or similar connection needs additional internal support.
How Does a Plastic Pipe Insert Work?
A plastic pipe insert is pushed into the open end of the pipe. It sits inside the pipe wall and supports the material from within.
Next, the pipe connects to the required fitting. The insert helps prevent the pipe from deforming too much when the connection is tightened.
This is important because a secure connection depends on the pipe keeping its correct shape. Therefore, using the correct insert can make installation easier and help create a reliable joint.
The process is simple, but the insert must match the pipe size and application.
How Are Plastic Pipe Inserts Made?
Most pipe inserts use a strong plastic material designed for use inside pipe systems. During production, the material is shaped into a small component with dimensions suited to a particular pipe size.
Manufacturers control the insert’s outer diameter, inner opening, length, and overall shape. These measurements matter because the insert needs to fit correctly inside the pipe.
Quality control also plays an important role. Each component should maintain consistent dimensions so installers can use it with the intended pipe system.
As a result, good plastic fittings should provide a reliable fit when used according to the product specifications.
What Is a 15mm Pipe Insert?
A 15mm pipe insert is designed for suitable 15mm plastic pipe. It provides internal support before the pipe connects to a fitting.
The 15mm size is common in many domestic plumbing applications. However, pipe material and fitting type can vary, so always check the product specifications before installation.
For example, a correctly sized insert can help the pipe retain its shape when a compression fitting is tightened.
What Is a 22mm Pipe Stiffener Insert?
A 22mm pipe stiffener insert performs the same basic function but is designed for suitable 22mm plastic pipe.
It supports the inside of the pipe and helps reduce unwanted deformation at the connection point. Therefore, it can be useful when working with larger plastic pipe systems.
PRODUCT: 22MM PIPE STIFFENER INSERT
The 22MM PIPE STIFFENER INSERT is available in various pack options. This can be useful for installers who need several inserts for a larger plumbing project.
Before you buy, check the pipe size and product details carefully. The correct size helps ensure the insert fits the intended pipe.
PRODUCT: 15MM Pipe Stiffener Insert
The 15MM Pipe Stiffener Insert is designed for suitable 15mm plastic pipe applications.
It can help support the pipe internally and provide a firmer base for a connection. Therefore, it is a useful component to keep available when working on domestic plumbing projects.
If you regularly carry out repairs or installations, buying the correct inserts in suitable pack quantities can make future jobs easier.
What Are the Advantages of Plastic Fittings?
There are several advantages to using plastic fittings and suitable pipe inserts.
Better Pipe Support
A stiffener insert gives the pipe internal support. This can help it maintain its shape around a connection.
Easy Installation
Pipe inserts are small and simple to handle. Once the correct size has been selected, the installation process is straightforward.
Useful for Plumbing Work
These components suit many plumbing applications where plastic pipes connect to compression fittings or other suitable components.
Different Sizes Available
Common sizes include 15mm and 22mm. Having different sizes available makes it easier to work on different pipe systems.
Practical for Repairs
Pipe inserts can be useful during maintenance and repair work. Keeping suitable sizes in your toolkit can save time when replacing or reconnecting pipe.
What Should You Check Before Buying Plastic Fittings?
Before you shop for plastic fittings, start by checking the pipe size. A 15mm insert should not be used where a 22mm insert is required.
Next, check the pipe material. Different pipe systems can have different requirements. Always follow the manufacturer’s instructions.
You should also check whether the insert is compatible with the pipe and fitting being used.
Finally, inspect the product dimensions and pack quantity. This helps you buy the correct number of components for your project.
How Do Pipe Inserts Help With Connections?
A Pipe insert sits inside the pipe and provides internal support. When the fitting is tightened, the insert helps the pipe resist excessive deformation.
This can be especially useful with compression-style connections. The pipe remains supported while the fitting creates the joint.
The insert itself does not replace the correct fitting or installation method. Instead, it works as part of the complete connection system.
A suitable Connector must still match the pipe and installation requirements.
Where Are Plastic Fittings Used?
Plastic fittings can be found in many plumbing and pipework applications. They may be used in domestic homes, commercial buildings, maintenance work, heating systems, and general plumbing projects.
Pipe inserts are particularly useful where plastic pipe needs internal support. They can help installers create cleaner and more secure connections.
Before installation, make sure the pipe is cut cleanly. Check the pipe end for damage, dirt, or an uneven edge. The internal area should also be clear so the insert can sit correctly.
Why Should You Shop for the Correct Pipe Insert?
Choosing the correct product can save time and prevent installation problems. A wrongly sized insert may not provide the required support.
Therefore, always shop by pipe size and application. If your project uses 15mm pipe, look for a suitable 15mm insert. For 22mm pipe, choose a suitable 22mm product.
Good plastic fittings selection starts with accurate measurements and careful product checks.
