The NEW 9mm spring was developed as a compromise between the more ridgid 8mm and more flexible but thicker 10mm… People were noticing the 8mm had difficulties passing bends which sometimes causes the 8mm springs to break and the 10mm is too thick to be used in DN40mm pipes.
9mm outside diameter, wire thickness 2.5mm, with a standard drill head or with a square coupling and with plastic sheathed inner core.
Available in various lengths, starting from 7.5 meter.
Suitable for all drum machines from Rioned HANDMATIC/FLEXMATIC/FLEXMATIC+, Ridgid K40/K45, Rothenberger RODRUM/ROSPIMATIC
