John Guest 12mm Fittings For Caravans

61 Products.

John Guest fittings are a key choice for easy and reliable plumbing solutions in the caravan industry. Known for their quick-connect Speedfit System, these fittings allow for tool-free installations, repairs, and modifications. Whether its pipe fittings, 12mm fittings, or connectors, John Guests range is designed for both professionals and DIY enthusiasts, ensuring a secure, watertight connection every time. This system simplifies plumbing projects, saving time and effort for all users.

There a two distinct lines of John Guest 12mm fittings available: The Classic Speedfit range and the Twist & Lock WaterMarked range. The WaterMarked range, introduced to comply with Victorian plumbing legislation, is identifiable by its white color and is required for hot water lines in caravans and motorhomes manufactured in Victoria. However, the original Speedfit range (black or grey colour) remains dominant in the rest of Australia.

The Classic Speedfit Pipe, known for its flexibility and durability, is made from semi-rigid LLDPE tubing. This makes it an ideal option for the tight spaces often found in caravan and motorhome installations. Conversely, the WaterMark Twist & Lock Pipe, crafted from white BPEX, offers enhanced strength and is better suited for managing higher water temperatures, though it is slightly less flexible.

While a 15mm range is also available, the 12mm size remains the favourite among the Australian RV community. John Guests comprehensive selection of fittings for this size ensures that users have access to versatile and reliable connections for their caravans and motorhomes. The WaterMark Twist and Lock Fittings are designed to be compatible with both BPEX and Classic Speedfit Pipes, enhancing installation flexibility. Additionally, the WaterMarked range includes brass BSP adapters, facilitating a seamless connection to hot water systems.

Renowned for their versatility, reliability, and widespread preference in the caravan and motorhome sector, John Guest connectors and fittings represent a top choice across Australia.
