What’s so super about Pipe Inserts anyway?

If there’s one benefit every installer can expect from Speedfit fittings, it’s a secure and reliable, leakproof connection. This is made possible through a combination of our unique push-fit & twist and lock mechanism, as well as the use of pipe inserts and super-seal inserts.

In this blog post, we look at the importance of plain inserts and superseal inserts, outlining everything you need to know about these essential plumbing products.

 

Speedfit Inserts

 

Why do we use Pipe Inserts?

Inserts play a vital role in providing extra support to pipework, ensuring that the ends of the pipe are kept nice and round, and minimising any loss of shape that can occur when cutting.

By maintaining the structural integrity of the pipework, inserts facilitate a more effective seal between the outside diameter of the pipe and the O-ring. In turn, this helps to make the pipe more rigid when a side load is applied.

Plumbers and installers must use a Speedfit pipe insert when working with our products.

Push-fit Plumbing Inserts

 

What’s the role of a Superseal Insert then?

 

A superseal insert adds an extra line of defence to fittings and pipes. What makes them unique is the fact that they feature two additional O-ring seals compared to plain inserts. One of these is located on the stem, which is pushed into the pipe to prevent water from inside the pipe passing between the inside of the pipe wall, and the outside surface of the insert.

The other O-ring sits on the end of the insert and seals inside the fitting, in effect becoming the primary seal between the pipe and the fitting.

 

 

How do I know which Insert Type I need for Each Project?

 

While both types of pipe insert are suitable for hot and cold-water systems as well as underfloor heating and central heating, when using Speedfit pipe and fittings, a plain insert should always be used when plastic pipe is installed with a compression fitting.

Compression fittings vary in terms of depth and in some cases, using a superseal may stop the pipe from going fully into the fitting to ensure the compression ring is sitting on the pipe, and not on the insert.

Always check that the compression fitting is suitable for use with plastic pipework and follow the instructions.

How do I ensure I always get Maximum Performance from my Inserts?

 

Inserts can only perform to a high standard when the O-ring is protected from dirt and grit, as particle ingress can lead to leaks.

Basic housekeeping, such as ensuring plumbing inserts & fittings are kept clean and stored safely, can help prevent this risk and ensure that inserts always perform to a high standard.
