JG Speedfit Superseal Pipe Inserts are an essential component for achieving a secure and reliable connection when using Speedfit push-fit fittings with plastic pipework. These precision-moulded inserts are designed specifically to enhance the sealing performance of joints by supporting the internal structure of the pipe and incorporating dual O-rings for a watertight fit.

Available in 10mm, 15mm, and 22mm sizes, each insert is manufactured for use exclusively with Speedfit pipes and fittings, offering additional grip and seal security, especially for central heating systems where durability under pressure is critical.


Key Features:

  • Enhanced Sealing Performance:
    Dual O-ring design ensures a more secure seal than standard pipe inserts.
  • Pipe Support:
    Prevents deformation of plastic pipes, especially when under compression or heat.
  • System-Specific:
    Must be used only with Speedfit pipe and fittings for optimal performance and compatibility.
  • Ideal for Central Heating:
    Fully suitable for use in high-temperature systems including sealed and open-vented central heating.
  • Easy Installation:
    Simply push into the end of the pipe before connecting to a Speedfit fitting.

Frequently Asked Questions (FAQs):

Q: Can these inserts be used with copper pipe?
A: No. Superseal inserts are designed for use only with Speedfit plastic pipe and are not compatible with copper piping.

Q: Are these required when using Speedfit fittings?
A: Yes. When using plastic pipe with Speedfit fittings, the use of Superseal inserts is strongly recommended to maintain the integrity of the connection and ensure leak-free performance.

Q: How do these differ from standard inserts?
A: Superseal inserts feature a dual O-ring design, offering greater sealing security and are specifically intended for systems under higher pressure or temperature, such as central heating.

Q: Do I need any special tools to fit these?
A: No special tools are required. Simply push the insert fully into the end of a clean, cut plastic pipe before connecting to the fitting.

Q: Can these be reused?
A: It is not recommended to reuse pipe inserts once removed, as this may compromise the sealing integrity.
