* The ISO size corresponds to the internal diameter of the hose or the external diameter of the rigid tube (as defined in ISO 4397 Standard)
** Indicated values refer to a 1 bar/14.5 psi pressure drop
*** 400 bar for static, steady or non-pulsed applications, 350 bar for ISO pressure rating for dynamic applications with moderate hydraulic shock
European Pressure
Equipment Directive
All couplings are designed and
manufactured under Article
4.3 of the European Pressure
Equipment Directive PED
2014/68/EU. Couplings with
nominal diameters greater than
25 mm should not be used
to convey gases in Group 1
(hazardous).
