Also available to special order are the 'H3 Series' 'Hi-Flow' couplers, which have larger diameter coupling mechanisms to allow for larger valve chambers and therefore increased flow capacity. These couplings have the standard hose side termination i.e. 1/2" Bsp but are not interchangeable with the standard 1/2" plug.

An 'H3 Series' ISO 16028 Flat Face 1/2" standard and 'Hi-Flow' can be seen below for comparison.
