Guardian Equipment's 470-005R is a set of six replacement 1.8 gallon per minute (GPM) flow controls for the GS-Plus™ spray head assemblies (item # AP470-001) used in Guardian Equipment eye/face washes. IMPORTANT: In order to operate properly, the flow control must be inserted into the spray head body concave end first. An exploded parts diagram for the GS-Plus™ spray head is available which makes this more clear.
Note: Effective January 1, 1997, The GS outlet head was replaced by the GS-Plus™ spray head. Rather than installing replacement component parts for the GS head, the manufacturer recommends replacing the entire head with a GS-Plus™ spray head.
