Eheim valve for hose 12/16

This valve is made for a tube-tube connection. Push the hose over the nozzle and turn the fixation ring counter clockwise until the hose will not drop. Also you can connect this valve into the female G1/4" thread. Therefore turn off one fixation ring and screw the valve in a suitable thread - if necessary use teflon tape oder silicone glue.
Use only fexible soft PVC hoses (too old and brittle hoses must be changed). Silicone hoses are suitable, too.
