This is for 1 set of o-rings... the front half or fluid housing / wet assembly are chemical resistant, the back half or dry portion are regular. You can cook these in Dynasol if you want and they will remain the same.
ONLY EVOSPRAY OFFERS PREMIUM O-RINGS THAT ARE THE SAME AS GRACO.
EVOSPRAY sells the finest products available at the lowest prices.
If you want cheap inferior replacement parts shop with the others.
