Clause 3.4 of AS 2419.2-2009 and clause 3.5 of AS 2419.3-2012 specify that Storz hose connections shall be manufactured in aluminium or copper alloy using forged processes.
FlameStop manufactures a range of NEN 3374 forged Storz adapters, compatible with various 65mm threads, providing 65mm Storz hermaphrodite connections for hose connections.
Cast and semi-cast aluminium Storz hose connections have failed when connected hose has been pressurised. This presents a serious risk to the safety of firefighters and the public, and compromises the use of the fitting. FlameStop Storz adapters have been tested to 16 Bar / 1600kPa.
