Created for connecting to 1/2″ male threaded fittings. The other end connects to hose/pipe measuring 13 mm internal diameter fitting LDPE pipe and most standard garden hose and is Hozelock compatible. The BSP connector includes a rubber washer for a watertight fitting so PTFE tape is NOT required. We sell both 1/2″ and 3/4″ 16mm valves in both male and female BSP connections. To ease fitting of the hose/pipe, please gently warm the pipe it’s being fitted into.
