I haven't had an opportunity to go to Home Depot to look up part numbers or take pictures yet but I can tell you a bit about how I accomplished the spray attachement.
What you want is a dishwasher adapter in place of your aerator. Years ago they had stand alone roll around dishwashers and this fitting would adapt your faucet to the dishwasher. Take your aerator with you for proper thread sizing. If Home Depot does not have it try your local plumbing supply. If I recall it did take a couple more fittings to adapt down to an appropriate size hose barb ( 1/4 in. or so )
On the spray end I used a fitting with the hose barb on one end and threaded a female cap on the other. I then experimented with a couple size drill bits to get the pressure I wanted. I do recall I ended up smaller than 1/8 in.
Now, having described all that, the truth is I don't use that sprayer any more because even though my water is filtered it bugged me to use tap water.
I now mount my records on the home built Gem Dandy, spray them with record cleaner ( of your choice ) scrub the record with a natural bristle paint brush, let it soak for a couple of minutes and then steam with the Perfection Steamer purchased at Walgreens. I then rinse with a hand held spray bottle utilizing Peak demineralized water ( also used in the steamer ) purchased at Pep Boys.
I would like to build an auto drier sometime in the near future but for now I dry with a micro fiber cloth and then air dry for a couple hours in a rubberized dish rack.
You can find a wealth of information regarding steaming right here in the steam cleaning records thread.
I can't take credit for any of this I just took in the information and adapted the various devices to suit my needs.
