Product Information
Full details
The John Guest Speedfit 12mm Tube Insert (TSM1209S) is an essential component designed for professional plumbers and DIY enthusiasts who require secure, leak-proof connections in plastic plumbing systems. These inserts provide the necessary structural support to prevent pipe collapse or disconnection at fitting points, ensuring long-term system integrity. While they are engineered for simplicity, it is important to note that they must be used specifically with compatible 12mm pipe to ensure a proper, pressure-rated seal.

FAQs
Are these inserts reusable?
Yes, if they are undamaged during the disassembly of the connection, they can be reused.
Do I need special tools for this?
No, the Speedfit system is designed for hand-assembly only.
Can I use this with metal pipes?
No, these inserts are specifically designed for use with plastic pipe systems.
Is there a specific orientation for the insert?
The insert should be pushed into the pipe end until it is flush with the pipe opening.
What happens if I forget the insert?
Using Speedfit pipe without the proper insert can cause the pipe to collapse under the fitting's pressure, leading to leaks or accidental disconnection.
Troubleshooting
Difficulty inserting the pipe into the fitting
Ensure the pipe is cut squarely and the insert is pushed completely flush with the pipe end.
Connection is leaking
Verify the pipe is pushed past the O-ring to the full depth of the fitting and that the insert is present inside the pipe end.

Setup, Compatibility & Care
To install, ensure your 12mm pipe is cut cleanly and squarely using a pipe cutter. Slide the TSM1209S insert fully into the end of the pipe. Once inserted, the pipe can be pushed directly into the Speedfit fitting until it reaches the stop. For maintenance, regularly inspect your plumbing connections for signs of moisture. If a pipe needs to be removed for adjustment, follow standard Speedfit release procedures: push the collet against the fitting body and pull the pipe out while ensuring the insert remains in place or is retrieved if necessary. Keep unused inserts in a dry, cool environment to prevent degradation of the material.
