3”3”
3” for model 150 guns) and (4”4”
4”4”
4” for model 200 guns). The bolts which
are needed for connecting the ANSI flanged gun must have thread 1/2-13 UNC-2B. This thread is tapped into the holes which are used for
connection of the flange to the riser flange. To get the 4” ANSI flange on the F200, an adapter is required (part #10565). The (8) flange holes are
threaded 1/2-13 UNC-2B. The adapter (part #10565) is sold separately. Bolts for the (8) threaded holes are not shipped with the flange adapter.
