This 15mm plain pipe insert is used with plastic pipes in plumbing installations to provide added support at joint connections. Produced from durable polyphenylene, it is designed to fit inside the pipe, helping to maintain shape and form under compression from fittings.
Typically installed when connecting plastic pipework to push-fit or compression fittings, the insert supports the internal wall of the pipe during assembly. It is suitable for water supply and central heating systems, where maintaining reliable connections is required. The 48mm length and white colour fit with common 15mm plastic pipework, making it a standard component on site where plastic plumbing is being installed or repaired.
