USD valve washers

[colddiver]

Anyone know of any reserve stem washers available for a USD 3 piece tank valve? The schematic I have shows one washer but my valve has 3.

Me thinks someone put in two extra. I find this every now and then when someone wings it with no schematic and/or no knowledge of the older valves. The schematic is right, just one white teflon seal is all they use. The teflon seals are generic, any shop should have them but thats not saying much. Or get them here.
