Upgrade the reliability and performance of your plumbing system with the JG Speedfit 15mm Plastic Push‑Fit Superseal Pipe Insert—a premium, high‑integrity component engineered for secure, leak‑resistant connections. Designed exclusively for use with Speedfit pipes and push‑fit fittings, this 15mm Superseal insert enhances sealing performance and reinforces pipe structure, making it an essential choice for both professional installers and DIY plumbing projects.

Crafted with dual O‑ring technology, the Superseal insert ensures a superior multi‑layered seal. The first O‑ring sits on the stem to block water from travelling between the pipe wall and the insert, while the second forms a tight seal inside the fitting. This advanced sealing system significantly improves joint integrity and minimises the risk of leaks—particularly beneficial in high‑demand heating and water systems. 

The insert also strengthens the pipe end, helping maintain a perfectly round shape after cutting, preventing distortion, and ensuring the smoothest possible push‑fit connection. This increased rigidity supports long‑term durability, even when lateral forces are applied. Designed for hot and cold water services and central heating systems, the 15mm Superseal Insert is WRAS‑approved and manufactured to meet high‑level British and international standards, providing reliable performance across domestic and commercial applications. 

Whether you're installing new pipework or upgrading an existing system, the JG Speedfit 15mm Superseal Pipe Insert delivers unmatched sealing security, easy tool‑free installation, and long‑lasting dependability—making it the trusted choice for modern plumbing setups.
