It is a stainless hollow squirter screw that comes with two regular felt type gaskets and a .054" thick gasket/spacer (not shown in that picture). I have two if these in front of me and that is why I am asking the question. I have never heard of the spacers, so I am curious if anyone else on the board was using them.
I talked with QF about this and you can use one of the washers under the squirter (typical install), or you can use the spacer under the squirter to raise the squirter.
I added a picture of both kits. The washer beside the screw is the one in question. Sorry for the focus, it was taken with my phone.
Thanks for the response.
EDIT:
Note:
I like the allen head design and with a 5/32 ball end allen wrench, the screw "snapped" into the end of the screw. This allows a one hand install.
