đ§ WHY WE USE JOHN GUEST FITTINGS
Push-fit fittings are essential in campervan plumbing for creating fast, reliable, and easy-to-maintain systems.
The John Guest 12mm Isolation Valve allows you to quickly shut off water flow in a 12mm pipe system, making it ideal for maintenance, system control, and isolating components.
In van conversions, these valves are used to control water supply to taps, showers, and appliances.
