In July 2014 Major Manufacturers of Helms and related products changed hose fittings from an NPT style thread to O.R.B. Please confirm that your Helm ports are in fact O.R.B before attempting to install O.R.B. fittings. Using O.R.B. fittings on a NPT threaded port will cause permanent damage to your Helm. If in doubt, please contact your Helm Manufacturer to confirm which thread fittings you require. If your helm requires NPT thread fittings, please contact your nearest Octopus Products supplier.
