The John Guest 15mm to 12mm Push Fit Adaptor is designed to connect 15mm push-fit fittings to 12mm John Guest Speedfit or Whale semi-rigid pipe. It is commonly used when installing Bullfinch outdoor shower points, allowing a simple connection between the 15mm outlets on the shower point and standard 12mm leisure vehicle water pipe.
Installation is quick and straightforward. Simply push the 15mm stem into the Bullfinch shower point or compatible 15mm push-fit fitting, then push the 12mm semi-rigid pipe fully into the adaptor. The push-fit connection creates a secure, leak-resistant seal without the need for tools, solvent or sealants.
