JG Speedfit 15mm Pipe Insert – High‑Strength Support Insert for Plastic & Soft Metal Pipe

The JG Speedfit 15mm Pipe Insert is an essential component for ensuring strong, secure and long‑lasting push‑fit pipe connections. Designed to provide internal support, this pipe insert helps maintain a perfectly round pipe end, reducing deformation that can occur during cutting or installation and ensuring optimal sealing performance.

Manufactured in the UK from high‑performance polyphenylene, the insert reinforces the pipe wall and significantly improves rigidity under side load, helping to maintain joint integrity over time. This makes it particularly valuable in push‑fit plumbing systems where reliable connections are critical for system efficiency and safety.

Suitable for use in hot and cold water systems as well as central heating applications, the JG Speedfit 15mm pipe insert is compatible with plastic and soft metal pipework, delivering versatility across a wide range of domestic and light commercial installations. By minimising pipe ovality and supporting the fitting seal, it helps reduce the risk of leaks and connection failures.

Certified to BS 7291 standards and Kitemark approved, this insert offers installers confidence in compliance, quality and performance. Whether used in new installations or system maintenance, it provides a simple yet highly effective solution for enhancing the durability and reliability of pipe connections.
