The John Guest Speedfit 12mm Pipe Inserts are designed to support 12mm semi-rigid water pipe when used with John Guest Speedfit push-fit fittings. They help maintain the internal shape of the pipe, ensuring a secure, leak-resistant connection and reliable long-term performance.

Pipe inserts should always be fitted inside 12mm John Guest Speedfit and Whale semi-rigid pipe before inserting the pipe into a push-fit fitting. They provide additional support to the pipe and help the O-ring inside the fitting create a consistent seal.

Manufactured from durable engineering plastic, these genuine John Guest inserts are suitable for hot and cold fresh water systems in caravans, motorhomes, campervans, boats and horseboxes. Available in a range of pack sizes to suit everything from small repairs to complete vehicle conversions.
