The John Guest Speedfit 12mm Female to 1/2" BSPP Female Adaptor is designed to connect 12mm John Guest Speedfit or Whale semi-rigid pipe to a 1/2" BSPP (British Standard Pipe Parallel) male threaded fitting. It is ideal for fresh water plumbing systems in caravans, motorhomes, campervans, boats and horseboxes.

Installation is quick and straightforward. Simply push the 12mm semi-rigid pipe fully into the Speedfit connection and screw the adaptor onto a compatible 1/2" BSPP male thread. The push-fit connection creates a secure, leak-resistant seal without the need for tools, solvent or sealants.

Manufactured from durable, corrosion-resistant acetal, this genuine John Guest fitting incorporates stainless steel grip teeth and an internal O-ring to provide a reliable connection. It is fully demountable, allowing pipework to be disconnected quickly for servicing or maintenance.
