John Guest 15-12mm Straight Connector Speedfit Connector PPM201512W

The John Guest 15mm to 12mm connector provides a simple way to connect 15mm and 12mm semi-rigid water pipe within campervan, caravan and motorhome plumbing systems. With a push-fit connection at each end, it can be installed without tools, hot works or sealing agents.

Designed to connect two unequal metric pipe sizes, this fitting has a 15mm push-fit connection at one end and a 12mm push-fit connection at the other. It can therefore be used when reducing a 15mm water supply to 12mm pipe or when connecting the two sizes in the opposite direction.

Manufactured from white polypropylene with a food-grade EPDM O-ring, the fitting is suitable for potable water, water treatment and intermittent hot water applications. The push-fit design creates a secure, leak-tight connection while remaining fully demountable when access or maintenance is required.

John Guest 15mm to 12mm Connector for Water Systems

The John Guest reducing connector uses the manufacturer's collet locking design to securely hold the pipe without deforming it or restricting flow. Installation is straightforward: the correctly prepared pipe is pushed into the fitting to create the connection, making it particularly convenient for leisure vehicle water systems where space can be limited.

This John Guest straight connector is compatible with suitable LLDPE or soft metal pipe and tubing. For campervan and motorhome installations, it provides a convenient solution when joining compatible 15mm and 12mm semi-rigid water pipe.
