John Guest Speedfit
12mm x 3/8" BSP male adapter
John Guest Speedfit is an easy to use, plastic push-fit system suitable for the plumbing of hot and cold water. The flexible piping system significantly reduces installation time without the need for specialist tools and the fitting can be easily removed if required. Extensive tests have shown that Speedfit products will withstand temperatures and pressures well in excess of normal working conditions.
Note: With all plastic pipes the relevant manufacturer's pipe insert is required.
