💧 WHY WE USE PIPE INSERTS
Pipe inserts are an important part of push-fit plumbing systems, especially when using soft or flexible tubing.
They reinforce the inside of the pipe, helping maintain the correct shape and ensuring the push-fit connector can seal properly.
In campervan water systems where vibration and movement are common, inserts help improve reliability and reduce the risk of leaks.
They are small components, but we strongly recommend using them whenever installing 12 mm push-fit plumbing systems.
If you're unsure whether inserts are required for your setup, we're happy to help before you buy.

12 mm Pipe Insert (John Guest Compatible) is designed to support and reinforce 12 mm plastic tubing used with push-fit plumbing fittings.
The insert fits inside the pipe and helps prevent deformation when the pipe is inserted into a push-fit connector. This ensures the fitting seals correctly and maintains a secure connection in pressurised water systems.
These inserts are commonly used in campervans, motorhomes, boats, and off-grid water systems that use 12 mm push-fit plumbing components.
