The MK2 nozzle holder is a handy way to attach spray nozzles to pipe work. The holder clamps around the pipe and a spigot with an o-ring inserts into a pre-drilled hole in the pipe. This attaches the clamp holder and forms a seal suitable for liquid pressures up to 4 bar (6 bar for the double clamp). The holder has a female thread to take any threaded nozzle. This product eliminates the need for threads to be tapped into pipe work, saving time and money.
