These complete AP470-021 FS-Plus™ spray heads are used in Guardian Equipment eye/face washes, have a 1/4" NPT female inlet and are 2" (5.1 cm) in diameter. Please measure your existing heads to make sure you don't need the smaller (1-1/2" diameter) GS-Plus™ spray head, item # AP470-001, instead. Parts diagrams for Guardian eyewashes (2 GS-Plus™ heads), eye/face washes (2 FS-Plus™ heads) and WideArea™ eye /face washes (4 GS-Plus™ heads) are available and if you still aren't sure which spray head you need, just send us an email with a picture of your eyewash and/or Guardian model number and we'll be happy to assist you (try that with Amazon, folks...).
This item is sold individually, but most customers usually purchase them in multiples of two.

Individual components of this spray head are also available for purchase. Replacement filters are economical and should be checked/replaced on a regular basis depending on the quality of your water supply. And every now and then someone will break off a dust cap lid. However, in many cases it may be easier and more economical to purchase a whole new head:
