John Guest Parts

John Guest is one of the most trusted brands in camper van and caravan plumbing, known for its innovative push-fit technology. These fittings allow you to connect pipes securely without the need for tools, clamps or complex installation processes—simply push the pipe into the fitting to create a strong, watertight seal. This makes them ideal for both DIY builds and professional installations, significantly reducing installation time while maintaining high reliability.

The Wired Campers collection includes a wide variety of John Guest components such as straight connectors, elbows, tees, reducers and pipe inserts, typically designed for standard 12mm water systems commonly used in camper vans. These fittings are perfect for building or modifying fresh water systems, connecting pumps, taps, tanks and appliances with ease.

One of the key advantages of John Guest fittings is their flexibility and reusability. Connections can be easily disconnected and reconfigured if needed, making them ideal for evolving camper van builds or future upgrades. Their secure locking mechanism ensures a tight seal while still allowing for easy maintenance or system changes without damaging components.

Designed for use in demanding environments, John Guest parts are highly resistant to pressure, temperature changes and vibration—making them perfectly suited to mobile applications such as camper vans and motorhomes. Their compact design also helps keep plumbing layouts neat and organised, especially in tight spaces where efficient routing is essential.
